Enteric Fever:- Part 2 – Typhoid Fever Diagnosis, Widal test, Its Procedure and Interpretations
Widal test
Enteric fever
Sample for Enteric fever
- It is done on the serum of the patient for the widal test.
- A random sample can be taken.
- For blood, culture collects the blood in sterile test tubes or specialized culture tubes.
- For urine culture, clean the area and then collect the mid-stream sample.
- Stool culture samples may be collected in sterile containers.
- Bone marrow, if needed, will be done with all precautions and sterilely.
Purpose of the test (Indication)
- This test is done to diagnose enteric fever (Typhoid and paratyphoid fever).
History of the Salmonella infection
- Diseases caused by salmonella are divided into two groups:
- Typhoidal infection by S.typhi and S.paratyphi.
- Humans are the only host of these pathogens, spreading person-to-person or via contaminated foodstuffs and water.
- Non-typhoidal infection from all other organisms.
- The most common non-typhoidal organisms in the USA are S.typhimurium and S.enteriditis.
- Of these infections, 95% are food born.
- Typhoidal infection by S.typhi and S.paratyphi.
- History of widal test:
- In 1896 widal test was discovered by George-Fernand Widal for the diagnosis of enteric fever.
- Enteric fever includes typhoid and paratyphoid fever.
- Paratyphoid fever is milder than typhoid fever.
- Enteric fever is also called typhoid fever.
- Typhoid fever is caused by the bacterium Salmonella Typhi.
- Salmonella typhi has an incubation period of 14 to 21 days. Sometimes may even be longer.
- 30% of the cases become chronic carriers due to persistent gallbladder infection.
Typhoid fever’s typical symptoms
Antigens and the antibodies of the salmonella typhi:
- H antigen: This is flagellar H antigen.
Typhoid bacilli structure
- Vi antigen is a polysaccharide capsule that surrounds the O antigen.
- It will protect the bacteria from the antibody attack on the O-antigen.
- This antigen is also called Vi for virulence.
- O-antigen is also called a somatic antigen.
- The Lipopolysaccharides antigen is somatic or O antigen.
- When there is a high titer of this antigen-antibody indicates acute fever.
- This will rise early and disappear early before the disappearance of the H-antigen.
- Antibodies:
- There are three respective antibodies:
- Anti-O antibody.
- Anti-H antibody.
- Anti-Vi antibody.
Diagnosis of Typhoid fever:
- WBCs decrease and may range from 4000 to 6000/cmm during the first two weeks.
- 3000 to 5000/cmm during the next 2 weeks.
- WBCs count around 10,000/cmm or more may suggest perforation of the intestine or suppuration.
- The peripheral blood smear shows normocytic anemia.
- In case of bleeding, anemia may become hypochromic and microcytic.
- Blood culture is positive during the first 10 days of fever in 90% of the cases.
- <30% positive after the third week of illness.
- Stool cultures are positive after the 10th day of illness, increasing frequency up to the 4th or 5 the week.
- Stool culture-positive after the 4 months indicates carrier state.
- Urine culture is positive during the second to the third week in 25% of the cases, even if the blood culture is negative.
- The widal test is positive after 7 to 10 days of infection. O and H antigens are found.
- There is an increase and a peak in the third to the fifth week of infection.
- After that, the titer starts to fall for several weeks.
- O-antigen appears before the appearance of the H- antigen.
- The rising titer of O-antigen is very important for the diagnosis.
- During the convalescent stage, the H-antigen is higher than the O- antigen.
- Positive widal test may be seen in:
- Typhoid fever.
- After the vaccination.
- In the case of a previous infection.
- Early infection treatment will not raise the titer or remain negative or low.
- H-antigen has little value in the diagnosis of typhoid fever.
The procedure of the Widal test:
- Serial dilution of the patient’s serum is taken from 1:40 to 1:320
- Now add an equal volume of Salmonella antigen.
- This can be done as a Slide method or as a Tube method.
- When running in the tube, then incubate tubes for 12 hours or overnight.
- Prepare the serial dilution, as shown in the diagram.
Serial dilution in the widal test
Widal test reading:
It is done as follows and can read the result where the agglutination starts, as shown in the following diagram.
The procedure of the widal test and interpretation
The drawback of the Widal test:
- This test will be positive after 7 to 10 days of Enteric fever.
- Salmonella has five serogroups: A, B, C, D, and E, based on O somatic antigen.
- Based on H-antigen are 1200 serotypes.
- 7 to 10 days, antibody to D-somatic antigen appears.
- These antibodies against O antigens reach their peak within 3 to 5 weeks.
- H-flagellar antibodies appear later on.
- The titer of O-antibodies 1:80 is suspicious in unvaccinated patients.
- The titer of 1:160 is strongly suggestive of infection in unvaccinated individuals.
- The titer of 1:40 for Antibody to flagellar-antigen (H) are suspicious in unvaccinated individual.
- Titers are much higher in the vaccinated individual.
- Vi antigens for S.typhi is used to screen the carrier. Antibodies to Vi-antigen are positive in the carrier state.
Interpretation of the widal test:
- The highest dilution of the serum is noted where there is agglutination.
- If it ends at 1:320, then that is the titer.
- The Widal test interpretations:
The titer of the antibody Interpretations of the Widal test O-antigen = >1:160 Active infection H-antigen = >1:160 Past infection or immunized Rising titer = 1:40 to 1:80 to 1:160 Diagnostic
O-antigen
- Antigen-O will be positive in the acute stage, and the titer will be more than 1:160.
- O-antigen appears early and also disappears early.
H-antigen
- H antigen rises late and disappears late.
- It is positive in the recovery stage.
Vi-antigen
- This is an indicator of the carrier stage.
The false-positive test:
- It may be seen due to cross-reacting infections, including malaria.
Other diagnostic tests for the diagnosis of Typhoid (Enteric) fever are:
- Blood culture will be positive in the first week of the negative Widal test.
- Stool culture.
- 60 to 70% of cases are negative during the first week, and more patients are positive in the third week of infection.
- Stool, 90% of the cases, are cleared of the bacteria by the 8th week of infection.
- Urine culture.
- Bone marrow culture. This is a very sensitive test.
- In the bone marrow, 90% of the cases are positive despite antibiotic therapy if these are ≤5 days.
- Another serological test is Typhidot.
Typhidot test
- In this test, the serum of the patient is taken.
- This kit claims that enteric fever may be diagnosed in the first week of fever.
Interpretations of the typhidot test:
Interpretation of the Typhidot test in enteric fever
- The gold standard is the blood culture, where 90% of cases are positive in the first week.
- 50% of cases are positive by the third week.
- For better yield, centrifuge the blood and take a buffy coat for culture.
- Other samples are stool, urine, Rose spot, bone marrow, and gastric or intestinal secretions.
- When culture is done simultaneously on blood, bone marrow, and intestinal secretions, positivity is >90%.
- A small % becomes the carrier, and their stool culture remains positive for at least one year.

For Nonmedical (non-specialist) person explanation of Widal test (Enteric fever):
- Please advise the Widal test if the fever persists for more than 5 days and is constant. It does not touch the normal level.
- The titer of O antigen 1:40 is considered negative.
- Just see the O antigen titer if it is 1:160, indicating Enteric fever.
- If the O antigen is 1:80, repeat the test after 5 to 7 days, and now if the titer is 1:160, the rising titer again indicates acute infection.
- While the H antigen does not indicate acute infection or acute enteric fever.
Questions and answers:
Question 1: What is the significance of the O-antigen?
Question 2: What is the significance of the Vi-antigen?
Good write up.
Thanks
Thanks a lot.
Sir my test is
Sto 1:320
Sth 1:80
Spah 1:80
Spbh 1:40
I am taking cefixime ofloxacin from last 6 days
But fever not gown and also abdominal pain and tenderness and my platelets are 134 legs pain too much
Wat i can do
Sir S type o- 1:80
S type-H :1:160
S type-AH – 1:20
S type BH -,1:20 is it typhoid positive
O antigen is 1:80, which is borderline, while H antigen represents past infection or vaccination. Please repeat widal after 5 to 7 days, and let me know the result.
Good day sir my report test says
Sal tyhi O:D1/20. H1/20
Salm paraty O:A1/40 H 1/20
Salm paraty O:B1/80 H 1/20
Salm paraty O: 1/80 H 1/40
Good day sir my report test says
Sal tyhi O:D1/20. H1/20
Salm paraty O:A1/40 H 1/20
Salm paraty O:B1/80 H 1/20
Salm paraty O: 1/80 H 1/40
How do you know if someone is suffering from either typhoid fever or paratyphoid fever? What does these test results mean?
O : H
S. Typhi-80:40
S. Para A- 80:80
S. Para B- 80:40
S. Para C-40:80
I look forward to your response
Your figures are not written correctly. I think these values should be 1:80. This widal test is borderline; please repeat after 5 to 7 days. If values are increased, then indicate typhoid fever; if same or low, then no typhoid fever.
My daughter has viral fever..after 5 days again fever was in 100 degree in night…doctor told to take blood test..TH is +in 1:40dil,TH IS 1:80dil..Is t normal level or higher level..how long it take to cure.she is 9years old
This is not a complete report. Please check the O antigen titer; if that is 1:160, that indicates acute typhoid fever. H titer indicates past infection.
Widal test is explained in a very simple way.
Thanks.
Good evening sir my typhoid level is 1:160.can you please tell me it is normal or not and should I have to eat or not.
I have replied to your email. This titer is positive for typhoid fever, so you need treatment, especially if you have a fever.
1.80 typhoid fever when medicine use
O antigen 1:80 is borderline and this might have come down by the treatment.
Good day sir my report test says
Sal tyhi O:D1/20. H1/20
Salm paraty O:A1/40 H 1/20
Salm paraty O:B1/80 H 1/20
Salm paraty O: 1/80 H 1/40
What does it mean if someone has a 1:160
If it is O 1:160 means positive and you can repeat after 3 to 7 days, and you will find a rising titer.
Hello sir ..my widal test s typho o 1:320 and fever comes in my inside body 2 month normal fever ..
Dear
Your widal is positive. You need to take a course on antibiots.
Prof.Riaz
Dear
Your widal is positive. You need to take a course on antibiotics.
Prof.Riaz
What is it means if reaction shows 1:40 both H and O
I will say negative and advise you to repeat the widal test after 5 to 7 days. If there is an increase in the value, then I will say it is positive. If again the same value comes, then it is definitely negative.
Very well explainaton… Very useful
Thanks.
Thanks a lot
Sir in my widal test report typhi O is 1:80 and typhi H is 1: 40 with fever constant 102 with bitter tongue drymouth body pains
Your Typhi O 1:80 is borderline. What is your TLC? If it is low, then the possibility is typhoid fever. Or repeat widal after 5 to 7 days.
S type o – 1:80 S type H-1:160/ Ah -1:20/Bh : 1:20
O antigen 1:80 is borderline. Would you please repeat the widal test after 5 to 7 days? If this goes up like 1:160, it is positive; if it is the same or <1:80, then widal is negative.
Sir, i have 1:320 in thypoid result
And i took injection course for 3 days morning and evening …. 10 days pills paracetamol and antibiotic… Still i am having severe headache sir…
1:320 if it is O antigen, then definitely it is enteric fever. These antibodies will disappear after a minimum of one year. First O antigen will disappear and later on H antigen.
Very well explained…
Thanks.
I appreciate your write-up, as it’s has ease enlightened me on my test results.
T
thanks
Widal test done on 9/09/20 give S typhi titre 1:180 after 20 days repeat test shows O titer negative (Nil)
How fast O titre disappears.
Please explain
O antigen titer negative means no typhoid fever. But titer of 1:180 was indicative typhoid fever but when there is no rising titer then typhoid fever possibility is out.
Please let me know about the H antigen titer. Your results are Confusing because O antigen toter can not become 0 in just 20 days.
Please reply earliest possible.
Replied to your question.
If widal- O 1:160 and H 1:80
And after around 15 days of treatment; Typhidot says IgM is negative & IgG is also negative.
So whether typhoid has resolved or person had no typhoid earlier (at time of widal)….
My doubt is simply that if IgG indicate remote infection then, should it not be positive in typhidot??…..or if it is negative then, there was no typhoid????
Please reply as soon as possible.
IgM Typhidot negative means the acute phase of the enteric fever is over.
Sir i have widal test with report of Typ O 1:20+ 1:40+ 1:80+ 1:160- 1:320- 1:640-

Your titer is 1:80, this is borderline, you should repeat widal after 5 to 7 days. If now it is 1:160, then it favors enteric fever. If it is the same at 1:80, then less likely of enteric fever.
Good Evening sir
My widal report is
S typhi o 1:320
S typhi H 1:80
S Para Typhi AH 1:20
S Para Typhi BH 1:20
But I don’t have fever, had slight back pain Body pain and cold
Kindly suggest
These values favor the diagnosis of enteric fever.
Good Evening sir
My widal report is

Sir ,pls I need your help
S typhi(0) less than 80
Typhi 160 H
Paratyphi less than 80
S.Paratyphi less than 80
Bruccella app less than 80
1:80 test report is borderline, can take it as negative. Repeat the test after 5 to 7 days. If there is an increase in the value, then the test will be positive.
Good Evening sir
My widal report is
S typhi o 1:160
S typhi H 1:80
S Para Typhi AH 1:40
S Para Typhi BH 1:40
I have a low grade fever of 99-99.2 and body pain. Have done the antibiotics course using ceftas for 15 days but there is no improvement in fever. I have fever from almost a month now.
Kindly suggest
Your widal test shows a positive result. You should consult some good physicians to change the antibiotics or find the cause of fever,
Good Evening sir
My widal report is
S typhi O Antigen Negative 1:20 Dil
S typhi H Antigen Positive 1:40 Dil
S Para Typhi AH Antigen Negative 1:20 Dil
S Para Typhi BH Antigen Negative 1:20 Dil
I have a low grade fever of 98-98.4 and body pain. Have done the antibiotics course using for 5 days there is improvement in fever. Cough is persistent
Kindly suggest
You should check your blood CBC and have an Xray chest,
Hi sir 6 days back my result is
Salmonella typhi O antigen 1:80
Salmonella typhi H antigen 1:160
And now
O antigen 1:80
H antigen 1:40
But from two days my fever got 103 degrees and 101 I am using monochef 1 mg daily morning and evening from two days
Is it going to be cured? Please suggest the answer asap
Now your widal test doesn’t favor typhoid fever.
Please consult a physician for a fever.
Are you suggesting that the fever was not because of typhoid?
Hi sir, for example, the result of the widal test if the is like this:
Dilution: 1:20
Reaction: +++
Dilution: 1:40
Reaction: ++
Dilution: 1:80
Reaction: ++
Dilution: 1:160
Reaction: +
Dilution: 1:320
Reaction: +/-
Dilution: 1:640
Reaction: –
What is my approximate antibody titer? Does the +/- can be considered since it is the highest dilution where agglutination occurs, hence, <25% of agglutination is seen?
1:80 O antigen-positive is borderline. Needs repeat the test after 5 to 7 days. If it is 1:160, then it is positive. If it is again 1:80, then it is negative.
Thank you so much sir it helps me a lot
Thanks a lot sir if you’ll happen to address my concern ❤️
please can you let me know the issue?
Good morning sir,
My widal report is
S typhi o 1:320
S typhi H 1:160
S Para Typhi AH 1:20
S Para Typhi BH 1:20
CRP : 0.6 mg/dl is there any viral infection? Please suggest me
Your widal test is positive. I don’t think you have a viral disease.
Hi sir..
Widal report..
S. Typhi O 1:80
S. Typhi H 1:80
Para AH 1:80
Para BH 1:80
Kindly guide..
These numbers are borderline. Please repeat the test after 5 to 7 days. If titer (number) increases, then the widal test is positive, if remains the same, then is negative.
Thank you soo much for your response sir. please clarify me one thing sir, CRP level 0.6 mg/dl is normal level or infected. Widal test is positive then CRP is very high?
CRP level is normal. You have not given the widal test report.
Please Doctor My widal test reads
Salmonella typhi O: 1:20
Salmonella typhi H: 1:20. Please Doctor is this test negative or positive. From Ghana, Navrongo.
Widal test is negative.
Good Evening sir

And today it’s increase
S typhi o 1:320
S typhi h 1:160
Sir Please suggest me what should I do.
I think you need to consult a good physician who should give you the right antibiotics.
My sis having S. T. O 1:80dil
S. T. H 1:80 is thz typhoid positive or high
Pllzzz sir tell me
Please let me know your question?
These numbers are borderline, please repeat widal after 5 to 7 days. If the number increases then it is typhoid fever. If the number is the same or decreased, then not typhoid fever.
Replied to your question.
My cousin widal report is
T’H – positive upto 1:80
T’O – positive upto 1:160
What does this indicate?
It favors typhoid fever. O titer 1:160 comes in a positive range.
Tnku so much sir
Sir, I am experiencing mild fever and weakness from past 10days.
My widal test report says-
S.typhi O – 1.80
S.typhi H- 1.80
What does this means?
These figures are borderline. Please repeat the widal after 5 to 7 days. If this is 1:160, then definitely it is typhoid fever.
In immunological practical examination, two students were given a same patient serum to test for the presence of Salmonella antibodies. One of the students made dilutions to the given serum up to 1:620 and got a positive result, while the other made the dilutions till 1:160, and he got a negative result.
can you answer this question please
The answer is very simple. When the antibody titer is very high then this will be negative in early dilution. You have to make more dilution to see the positive result.
This is called the prozone phenomenon.
In February,salmonella typhi ‘O’- dilution-1:160
Salmonella typhi ‘H’-dilution 1:160
H titer 1:160 indicates past infection. What was your O antigen titer?
Indicate borderline result if there is rising titer then definitely Typhoid fever.
Sir my widal test for all components come to 1.80, im having fever since last 30 days, back pain, headache & once had blood clots from stool & throat. Im having antibiotics since last 2 days named cebosh cefixime 200mg. Plz suggest something as feeling very week internally.
Your Widal test does not favor Typhoid fever. Please repeat your widal and have an X-Ray chest. If your ESR is very high, then you must consult a good physician.
My S titer ‘O’Brien is 1:40 and ‘ H’ is 1:80 and Ah and Bhai are negative but one month before this tst my report was O and H both titer are 0:80..and between this period still now my fingers, wrist snd ankle were swollen and hv lot of pain in moving them what to do is it positive or not
Please see your email.
Sir my result was s typhi O 1:40 positive and s typhi H 1:40 positive . Do i have typhoid fever?
This widal test is negative for typhoid fever.
Thanks doctor but why they mentioned positive in my report . Can you explain me this ?
Thanks Dr. You are doing a great job.I have learnt a lot.
Best regards
Edwin from. Nigeria
Thanks. I need encouraging remarks like yours.
Thanks, I need encouraging remarks like yours.
Thank you doctor .. you are clearing many doubts .. May Allah reward you immensely for this help..
Thanks, You are welcome.
Hi Doctor,
My Father who is 65 years old, is also diabetic. He is having a fever for the last 7 days.
O is 1.8
H is 1.8
AH non-reactive
BH non-reactive
What does this mean? Can you please help?
If this is 1:80, then this is borderline for typhoid fever. You need to repeat after 5 to 7 days. If it is the same, then there is no typhoid fever; if it is increased to 1:160, then positive for enteric fever.
sir my mother is ill from months her widal is 320 after medicines ger fever went to 100 and today again her fever rises to 103 what should i do?
I think the widal test may be repeated, and she needs to have a workup for PUO (pyrexia due to unknown reason). She needs consultation by a good physician and the lab workup.
S. Typhi O = 1/40
S. Typhi H =1/40
Does this values confirm Typhoid?
S. Typhi O = 1/40 ( < 160 repeat after 1 week . Two fold increase )
S. Typhi H =1/40 ( in titre confirms the Salmonella infection )
S. Paratyphi AH Negative ( Single Widal estimation is of little )
S. Paratyphi BH Negative
Does this values confirm Typhoid?
No, With these figures, the widal test is negative.
sir i have s typhi o 1:320
s typhi h 1:160
along with covid what should i do please advice.. i have headache low fever weakness white tongue for about 28 days..
I think you need treatment by some good physician. Your widal test is positive. You have to keep an eye on your body’s oxygen level. Oximeters are available, and these are not costly. Keep an eye that your body oxygen level should not go below 90% (normal level is 95% to 100%). Now recommendations are giving steroids and antiviral therapy.
Again I will suggest consulting a physician.
Hello Sir,
From the Widal test I showed antibodies to Salmonella typhi (O type Vi) and Salmonella paratyphi (H type b). I was very sick while on vacation in South America one year ago. My doctor doesn’t seem to know how to treat this. Am I a carrier and what antibiotics do you recommend? Thank you so much.
Please, what are the values of the widal test? If these are around 1:40, then widal is negative. I am sure your physicians must be the better judge.
In the picture under “Widal test procedure:”. Why are 1:20, 40, 80 are negative?
Because of the concentration and the ratio of antigen and antibody, only then will you see agglutination when the ratio is adequate.
In the picture under “Widal test procedure:”. Why are 1:20, 40, 80 are negative?
Report for 4 year kid

Please give your opinion as it is very hard to get blood test again done for kid.
Widal test O 1:80 is borderline. You have not written TLC and differential. Pain near the naval area needs to rule out appendicitis/ parasitic infestation. If the child has a problem for 14 days, then appendicitis is out. This child most likely may have a parasitic infestation. Please consult a good pediatrician.
Thank very much in replying very soon .I am very thankful to you ..your speedy reply on this post means a lot to me.I pary for your well being and progress in every aspect of your life .

If I plz tell what is Multiple enlarged mesenteric lymph nodes are seen largest at the root measuring 19*18.
hild specialist has being consulted just received online report and was worried .
TLC and DLC look normal. Rest mesenteric lymph nodes may be enlarged unless there is some history of fever and raised ESR. I will suggest you consult a good pediatrician for the possibility of parasitic infestation.
Thanks very much
Sir but my widal test o 1:40 and H 1:40. I have completed my course of 1 month and stopped taking medicine before 1 month now i chek my blood then results is 1:40 o, and 1:40 h what will I do plz sir ? Tell mr
This is the normal range. No need to worry.
Hi sir please reply
My Widal test
TO: 1/160
TH: 1/160
AH: 1/80
BH: 1/40
And in CBC everything normal sir what I do ?
Your widal O antigen 1:160 indicates acute infection. To confirm the diagnosis, repeat widal test after 5 to 7 days; if the O antigen is 1:320, that will confirm the enteric fever.
I had fever post that I took widal test which reads as
WIDAL Test (Slide Method)
SALMONELLA TYPHI `O` Negative In 1:20 Dilution
SALMONELLA TYPHI `H` Positive In 1:80 Dilution
S.PARATYPHI A `H` Negative In 1:20 Dilution
S.PARATYPHI B `H` Negative In 1:20 Dilution
Is this an indication of typhoid?
To me, this widal test is negative for an enteric fever—no need to worry about 1:20 titer and even antigen H.
Sir I have been feeling tired and lethargic for a week now. Did widal test and CBC today, below are observations, kindly share your expertise.
S Typhi O – 1:80
S Typhi H – 1:80
Platelet Count – 1.25 lakh/cmm
MCH – 33.56 PG
MCHC – 39.43 gm/dl
Rest all parameters in the reports suggest OK.
I must mention that you are doing a great service to the society. We need more great souls like you.

Please, how much were your ESR and TLC ?. 1:80 titer is borderline; please repeat Widal after 5 to 7 days. If the titer is high, then it indicates typhoid fever.
I have used malaria drugs twice and Cipro now table for typhoid after that I went for test and the widal test show S.Typhi O 1/40, H 1/160. S paratyphi A: O 1/20 H 1/20. S paratyphi B , O 1/40 H 1/160 . S paratyphi c , O 1/20, H 1/20 please explain it to me
H antigen titer indicates past infection or vaccination. In comparison, other antigens which indicate acute infection are in the normal range.
Dear sir,
Thanks a ton for your service and replys for every questions. I had no fevr but very exhausted and tired for last 1 week and here are my widal results
O 1:160
H 1:80
Para both negative.
Is it a severe infection dr? My physician given me mahacef plus oral antibiotics for 5 days. Just completed 1 day. Will you recommend iv antibiotics for this values?
Pls advice
Your O antigen 1:160 indicates typhoid fever. It would be best to get proper treatment (antibiotics) from the physician for the required days.
Hi sir
I was diagnose of typhoid but before I started treatment,
I did a CBC and my WBC was on numal range but my Lymphocytes level was 62% while my neutrophil was 33%.
I feel weak walking and also hav a white tongue.
Could u please explain this as am really bothered.
Thanks
CBC may be normal, but there is leucopenia which shows lymphocytosis. If you have typical typhoid fever and widal positive, then I think you should take the treatment. You will be alright.
S typhi ‘0’ 1:320
S typhi ‘H’ 1:40
S para typhi A (H) 1:40
S para typhi B (H) 1:40
Is it a severe infection ?
Widal test does not tell any severity of the disease. It is an only a diagnostic test for typhoid fever.
Sir please help out me I got tonsils in my throat as well as fever so I went lab and I checked in that typhoid o is 1:180 and thyphi h is 1: 80.is it typhoid fever???
O 1:180 indicates typhoid fever. You may have tonsillitis because of typhoid fever. When you take antibiotics for typhoid fever, it will cure tonsillitis.
Hi Dr. Riaz
My dad’s reports came out as follows:
Typhi O- 1:80
Typhi H- 1:160
P typhi (A H) – 1:80
P typhi (B H) – 1:160
TLC – 4400 (60% neutrophils)
Platelets: 1.3 lakh
ESR: 35
Lft’s normal and malaria negative
He had high fever for 5 days after which we got these tests done.
Does this look like typhoid?
He was started on Cefixime after seeing the results and it’s been 4 days since then. His fever has gradually reduced.
I’d be grateful for your advice.
Paratyphi B titer 1:160 suggests paratyphoid fever. TLC is also low. Overall picture favors paratyphoid fever. Record the temperature for 4 hourly for 48 hours, which will help the physician to reach the diagnosis. Physicians after the examination of the patient can give good advice.

Can you please Dr Riaz clarify why the first one was infection or vaccination and the second one was paratyphi B
The titer of H 1:160 is seen when the patients have a past infection or vaccination. This does not indicate acute infection. For acute infection, the Titer of O antigen is important. All O antigens are 1:40, which does not favor acute infection. This widal shows the recovery stage or post-vaccination.
Aoa Dr
My daughter having fever from last two weeks and we r giving antibiotics from many days as per Dr prescribed. We done with Widal test and results are
TO 1:160 positive
TH 1:160 positive
AO and AH negative
BO and BH negative.
Please advise about the results and what I will do for further treatment.
Thanks
Widal O titer 1:160 indicates typhoid fever. What are total leucocytes count? If it is low, then definitely it is typhoid fever. The patient is not responding to the antibiotics. She needs a change of antibiotics with the consultation of the physician.
Hello, my WIDAL report is H 1:20,1:40
And O is 1:20, 1:40, 1:80
Plz let me know is it typhoid

Gave ur opinion about the test result….am I in acute stage or I m a carrier…bcz I have same fever in last year not didn’t take antibiotics bt it went..bt now for month again fever came up
Your widal test is positive, and it shows acute stage. You have to take antibiotics for at least 2 weeks. And every year, you should get the vaccine for typhoid fever. Antibiotics must be advised by the physician.
Sir is my stage is severe…I m very scared now….can I get well from these antibiotics….is the typhoid fever can damage any of my organ…as it as from last year and did not treat thn as the fever goes out

Hello Sir,
My mom’s widal test result came as below:
Salmonella typhi O (TO) : Reactive upto Titre 1:320
Salmonella typhi H (TH) : Reactive upto Titre 1:160
Salmonella paratyphi A, H (AH) : Non Reactive
Salmonella paratyphi B, H (BH) : Non Reactive
What it shows?
These titer suggest widal test positive and she needs treatment.
Sir my reports says:
S.Typhi ”O”
1:20 +
1:40 +
1:80 +
1:160 +
1:320 –
1:640 –
All other S. Typhi H, P.Typhi AH, P.Typhi BH are Negative.
What does this means? Please Guide
S.typhi is 1:160 positive, which indicates infection or widal test positive.
My father Widal test results as follows sir:
O – 1 in 160
H – 1 in 360
AH – 1 in 20
BH – 1 in 20
what stage of infection my father has at present sir? My father does not have fever but having shivering at night so got tested.
O titer is 1:160, which indicates acute infection. While H antigen indicates late stage and it will be positive longer than O antigen. Anyhow this widal indicates acute stage.
Hello sir
detected covid 0n 09 apr and also detect typhi positive on 18 apr with range o : 160, H 80, AH: – ,BH: -.
Repeat wedal test on 5 may with range o : 80, H 80, AH: – ,BH: -. But from past 2 day i have a fever and body pain, my pulse also increaae to 130 to 150. I ALSO feel some uneasyness.
Your widal on April 18 was positive, and at the same time, you were covid positive. Covid is usually negative in 14 days. Now widal O 1:80 is borderline; if you repeat widal after one week, if the values are the same, then it is negative if titer of O is >1:160 means positive. I think you should have done a complete blood examination, which may help with the diagnosis. Also, check covid antibodies.
Hello Sir,
My Widal Test on 06/05/21 & the results as

Your first widal test was positive (O:160 +). I think you should complete the treatment for typhoid fever.
Sir my test resul is
O 1:320 +
H 1:320 +
What medicines should I take
Your widal test is positive, indicating typhoid fever, and as regards the treatment please consult the physician.
Hello doctor,I have done the widal test and the report was o-1:80 and h- 1:40 and A and B was negetive.but after contacting my doctor and taken complete 1week medicine was paracetamol but my fever was maximum 100.4 and ceprofloxican.and again taken test today and result is o- 1:80 and h- 1:80 and A and B is still negetive.please suggest me.
Your widal test looks negative because there is no rising titer of O antigen 1:80. On both occasion is same. H antigen indicates past infection or vaccination.

Hello sir
Initially I was suffering from malaria (Plasmodium vivax) Just after malaria I have low grade fever,weakness all the time and in CBC both malaria and typhoid were negative, After 10 days I again go for CBC and result is given below
My Widal test on 25/04/2021 and the result as
O=160+
H=160+
AH=40+
BH=40+
TLC=8500
Lymphocytes=42 % (High)
Monocytes= 01% (Low)
And all other values are in range
Doctor advise me for ciproflaxacin,paracetamol, neurokind etc.
But still the fever as earlier fluctuates between 99 and 100F resulting in much more weakness,fainting,mental confusion,low appetite, head temp high.
I again go for CBC on 12/05/2021 and result as
O=160+
H=80+
AH=40+
BH=40+
TLC=7290
Polymorph=42% (Low)
Lymphocytes=51( high)
Sir still my condition is same as earlier
Sir please Give me some suggestions – Waiting
Thanking u
Your widal test favor typhoid fever. You have a low-grade fever. You should record 4 hourly temperatures. Also, get an X-ray chest as well. Sometimes typhoid fever does not respond to ciprofloxacin. TLC second time7290 /cmm does not fever typhoid fever where TLC is usually low.
Hello sir
Initially I was suffering from malaria (Plasmodium vivax ) ,it left a low grade fever and littile head ache after 10 days on
25/04/2021 my CBC report is-
O=160+

AH=40+
BH=40+
TLC=8500
Lymphocytes=42%
Monocytes= 01%
Doctor said it is typhoid and prescribe me for ciproflaxacin,paraceta dilo 650mg,neurokind forte etc.
But there is no relief in fever as it still fluctuates between 99 and 100F
After 15 days I again go for CBC report is
O=160+
H=80+
AH=40+
BH=40+
TLC=7290
Lymphocytes=51%

All other parameters are in range
Sir please give some suggestions – waiting

Already replied.
Good afternoon Sir
all parameters < 1:40
what does it mean – Positive or Negative
regards
Singh
< 1:40 means negative.
Sir my O=negative
And H=160 after taking antibiotics for 10 days, what doest it means sir?
Am I still positive?
Post typhoid levels of H antigen remain over a year. Even after vaccination H will be raised.
Hi Dr. Riaz,
First of all, a million thanks for giving your valuable suggestions.
My mom aged 60 has O (TO) 1:160 and H(TH) 1:80 ; Paratyphi A, H (AH) and Paratyphi B, H (BH) are non reactive and she does not have fever but sometimes complaints about pain in her legs below knee and burning sensation on her feet.
Please suggest.
Antigen O 1:160 suggests the widal test is positive for typhoid fever. Please record 4 hourly temperature charts. If we believe this test then she needs treatment for typhoid fever.
hello sir

i had fever around 10 days earlier but i dont have any pain wether abdominal or chest till now
should i go with thypoid medication prescribed to me
please reply
You have not mentioned that was the result. If this was positive till 1:640, then definitely this is typhoid fever. The fever will be normal within 3 to 5 days; if not, then change the antibiotics.
Sir my low grade fever 98-99.3f persisting from 22 nd april .At that time my typhoid titre was O-1:80 and H-1:80 . Now I get the typhoid test on 28 may. Now titre O negetive and H 1: 320. What does it means. I still have fever the same and headache as well.
H antigen titer 1:320 indicate past infection or post-vaccination of typhoid fever.
Sir I have had history of repeated typhoid fever.
Recently I had fever for which I was prescribed doses of prednisolone, Ciprofloxacin and azythromycin. After 15 days Widal test along with cbc and ESR was done. Widal test came negative
Yet ESR was 50, while leukocyte has increased to 20500, neutrophils to 95% and lymphocytes reduced to 4% which was initially 55% before the treatment.
What can be inferred from the results? Ha typhoid subsided or is it the effect of steroids that it shows negative.
Also I don’t experience fever now but do get muscle stretches and pain.
Your CBC is interesting because it indicates acute infection other than typhoid fever. Your raised ESR telly with the TLC and DLC. Widal test must show H antigen titer. Cortisone may interfere with the immune system and typhoid test. You should check your urine and have an x-ray chest.
Sir I have had history of repeated typhoid fever. Recently I had been prescribed methylprednisolone, azythromycin and Ciprofloxacin for fever. I had my tests done after the treatment where ESR was found to be 50, leukocyte has increased to 20600, lymphocytes has reduced to 4% which was initially 55% and neutrophils is 96, while Widal result shows negative in all titres. Has typhoid subsided or is it due to steroids that the results are negative. I do not have fever but still experience muscle stretches, pain and heat.
Please read my explanation.
Thank you for your response sir
I should have mentioned I had also had urine test done along with other tests. Urine test result is very normal. Also mauntax skin and chest x ray has been done
which are negative and completely clear and normal.
I keep getting typhoid like symptoms and fever every 5-6 months which gets relieved for some time after taking antibiotics.
Pls. Guide what should be done.
Thanks.

Your widal test indicates typhoid fever. But your antibiotics are not working, so please ask your physician to change the antibiotic.
Sir my test result is

Your widal indicates typhoid fever. Your temperature should be normal in 5 to 7 days. If not, then change the antibiotics.
Hi Sir!
I was having cold, cough and body pains. Went for test.
My widal test showed
S.typhi O: 1/20, H: 1/20
S.Paratyphi A O:1/20, H: 1/20
S. Paratyphi B O:1/320, H:1/40
S.paratyphi C O:1/20, H: 1/20.
What does it suggest?
I was given after taking it I’m still having cold and body pains.
Your widal test paratyphi B O 1:320 favors paratyphoid fever. It would help if you were treated for paratyphoid fever.

BO positive at 1/40 and BH negative
CO and CH negative

Hi Dr. Riaz,
Thanks you very much for your reply.
I make an error in the results. For the BH it’s positive. But I write negative. I think this has no impact on your conclusion.
Thanks
You are right.
Hello Doctor,
Widal report:
S.typhi (O) 1:40
S.typhi (H) 1:40
S. para typhi A (H) less than 1:20
S. para typhi B (H) less than 1:20
Is this considered as typhoid positive or normal. Is this serious?
Please advice.
Your widal test is negative. No need to worry.
Hi Sir,
in my report:
Salmonella Typhi O(TO) : 1:160 Reactive upto attire
I feel discomfort and irritation in full body….and confusion, headache, fatigue,,, frequent stool…this is happening since 3 months…I took some antiboitics and I dont have fever….do I have Typhoid or typhoid has damaged anything?
please share your number…
Salmonella O antigen titer of 1:160 is definitely positive for typhoid fever. Keeping in mind your history, please exclude other causes of your illness. It would be best to have a complete workup like liver function tests, complete blood count, X-Ray chest, and ultrasound abdomen. Then consult some competent physician.
Thanks Doctor. So, can we conclude that person doesn’t have typhoid?
Temperature is 99 F , NO cold/cough, ESR is 25 mm/1st hr and QBC for MP is Negative.
Is this normal Sir and how many days takes to recover? Please advice.
ESR is a perfect indicator of any abnormality in the body. This ESR is not significantly raised. Typhoid fever with treatment usually fever subsides in 3 to 7 days. Would you please record 4 hourly temperatures?
Sir
I have done all these tests….Abdominal ultrasound says accessive gas in the bowel… CBC is ok but platelets are going down from 3L to 1.5L
KFT , LFT are ok I have done test 1 month back.. X-Ray chest is normal…but I have neurological problems…alway tired, my brain doesnt work perfectly….when I eat probiotics it gets better little bit but after few days becomes same.
I want to do a video conference with you….is this a possibility?
Sir my titer is
S.Typhi Antigen O is 1:80 and Antigen H is 1:80 then after 7 days I do repeat test and the test result is S.Typhi Antigen O is1:160 and H is 1:160.please tell me sir I am negative or positive
The rising titer is always positive. So your widal test is positive.
Sir. Advise me on my Typhoid result.
Salmonella Typhi O is 1:160
Salmonella Typhi H is 1:320
Replied.
Hi Sir, My test result was reads as follow
TO. 1:160
TH. 1:320
Am I Positive?
What is the advice Sir?
Antigen O titer of 1:160 is positive, and if you have fever as well, you must get the treatment for typhoid fever.
Sir,
My S. Typhi O is 1:160
S. Typhi H is 1:160
S. Paratyphi AH is 1:160
S. Paratyphi BH is 1:160
Kindly Give ur opinion Sir…
1 week back i used to have fever 101-102°F . I was started with antibiotic cefakind cv twice daily on day 1 of fever itself. But since the fever did not subside i went for widal test ,TLC,CRP which came out as mentioned above.
My CRP is 0.3mg/dl.
My TLC is 5870
Malaria Negative
Dengue Negative
Covid Negative.
Now fever subsided and i m on ofloxacin and cefixime 200mg each twice daily but i m having severe abdominal bloating n hence feeling breathless.
Your widal test is showing positivity for Salmonella Typhi and Paratyphi. Definitely, it would be best if you had treatment for typhoid fever. If I am not wrong, antibiotics are given for a long time to prevent the carrier state. Later on, antibiotics are tapered.
Widal Test
O 1:160
H 1:320
Crp – 28.6mg/dl
MP negative
does this mean that infection is starting to reduce?
I had low grade fever since last 5 days, sore thraot, cough and cold. My doctor gave me zifi 0 tablets im taking it since 6 days but it is causing stomach bloating and breathlessness while sleeping. Should i tell doctor to change my medicines/
O antigen 1:160 indicates typhoid fever. The temperature will settle in 5 to 7 days maximum. If your temperature does not settle in 5 days, then change the antibiotics.
Sir my o antigen is 1:120and H is negative then is it positive for typhoid
O antigen 1:120 indicates a positive reaction for typhoid fever.
Typhidot +ve IgG IgM
Widal test +ve 1:320
H/oCholecystectomy
suggest treatment plz
Your typhidot IgG and IgM, and widal test positive for typhoid fever. In the case of cholecystectomy, your chances for the carrier are very negligible. I will suggest the aggressive treatment of typhoid fever.
Dear Sir,
Very nice article and well explained. My Widal test reports are following:
Salmonella typhi (O): Reactive upto 1:80
Salmonella typhi (H): Reactive upto 1:320
S.paratyphi A (H): <1:40
S.paratyphi B (H): <1:40
Is it a serious infection? I have had typhoid when I was a kid also. Please suggest, how to go about it.
O antigen is 1:80 is the borderline limit. You need to repeat the widal test after 5 to 7 days; if there is a rising titer, e.g., 1:160, then definitely typhoid fever, and if it is the same or lowers like 1:40, then no need to worry. At the same time, H-antigen indicates past infection or vaccination.
Thank you for your kind advice Doctor.
My Widal test results as follows sir:
TO – 1 : 160
TH – 1 : 80
AH – 1 : 40
BH – 1 : 40
what stage of infection i has at present sir?
Your widal test is positive because of TO 1:160 titer. This only suggests typhoid fever and will not tell about any stage of typhoid fever. Widal test is positive after 7 to 10 days of the onset of the fever.
My widal test result states :

I have cold, cough and body pain. Thanks sir
Your widal test shows borderline titers. While H antigen is raised and it indicates past infection or vaccination. If you have a fever, then please repeat widal after 56 to 7 days.
Pls lf my widal To 1/20 and widal TH 1/80
Your widal test is normal.
sir, HAD FEVER 104 FOR FIRST 3 DAYS NOW IN DAY TIME ITS NORMAL BUT IN NIGHT IT REACHES UPTO 104 AGAIN. my details are following:-
STO= 1:160
STH=1:160
SPAH:-NO AGGLUTINATION SEEN
SPBH:-NO AGGLUTINATION SEEN
Your widal test is positive.STO 1:160 indicates acute infection. A low TLC count will favor typhoid fever.
Thank you so much sir.. tlc is 4800,
Sir, Goodevening; Typhidot IgM – Reactive and Typhidot – IgG Non Reactive
Typhi O is 1:80
Typhi H < 1:20
Typhi AH <1:20
Typhi BH < 1:20
Typhidot IgM is positive for typhoid fever. Your O antigen 1:80 is borderline for typhoid fever. Would you please repeat the widal test after 5 to 7 days? If it is a rising titer, then typhoid fever is confirmed.

Sir am having typhoid o is 1:60 and h 1:40 I have take 15 day cource again after 15 days am getting mild fever and weekness not able to do works am I resistant to antibiotics
Your widal test antigen O 1:160 indicates typhoid fever. It takes time to become normal, at least one year. If you are running a fever, ask your physician to change the antibiotics.
My widal test report
S.typhi “O” -1:160
S.typhi “H” -1:40
S.typhi “Ah” -1:20
S.typhi “BH” -1:20
Should i take antibiotics treatment ,
No fever only headache
My widal test report

S.typhi “BH” -1:20
Should i take antibiotics treatment ,
No fever only headache.
Sir please reply
Your widal test is positive for typhoid fever. This is surprising that you had no fever. It would help if you changed the thermometer. Your O-antigen level 1:160 suggests that you need antibiotics.
Thanks sir. I will check with another thermometer for future fever readings and take antibiotics with doctor reference.
Hello sir
I have salmonella typhi o 1.40 and H 1.160 and my fever is 103f sir is it because of typhiod
Salmonella typhi O 1:40 indicates that there is no acute stage of fever. Salmonella H 1:160 indicates past infection or vaccination.
Hello sir ,
After 10 days antibiotics (zifi-o). Test repeated after 3days antibiotics stop. Reports as follow.
S.typhi “O” -1:320
S.typhi “H” -1:40
S.typhi “Ah” -1:20
S.typhi “BH” -1:20
And TLC- 8000

In first test S.typhi “O” is 1:160 and rest are same
Please i did a typhoid check up some time ago and i first had S Typhi o -1/160 and i took ciprolez TZ for fourteen days when back to do the check again and the result came as S Typhi H-1/320. I want to know how long it will take for the bacteria to leave my blood.
O-antigen disappears from the body in around 12 months, while H-antigen takes a longer time.
Dear Sir,
My father age 63 (dvr patient) – has fever since two weeks initially it was 98-99 and now it has risen to 104-105. Symptoms are Chills before fever, dry cough and muscle pain
Malaria is negative
Dengue is negative and chest x ray is clear.
Widal tests are –
Typhi O – Absent
Typhi H – positive (titre 1:30)
Ah titre – absent
Bh titre – Absent.
Blood culture report is also negative.
Please opine.
Many thanks.
You have not mentioned the blood picture. TLC and differential count will help to rule out chronic, viral, or acute infection. ESR is also needed; if it is raised, try to find the reason for this fever.
sir,
this is my result,do i have typhoid or not
O is 1:80
H is 1:80
Paratyphi AH and BH is positive .
Widal test is borderline. Do you have a fever? What is your TLC? Please repeat the widal test after 5 to 7 days. If these values are increased, it indicates typhoid fever; if the values are the same, then no need to worry.
When serological test shows past infection (IgG) positive is treatment necessary?
You are right; I don’t think that any treatment is needed in the case of a positive IgG person.
S. Typhi ‘O’ – Titre 1:40
S. Typhi ‘H’ – Titre 1:20
Is typhoid positive?
This widal test is negative for typhoid fever. If the patient has a fever, repeat the test after 5 to 7 days.
SALMONELLA TYPHI – O 1:320
SALMONELLA TYPHI – H 1:320
SALMONELLA PARATYPHI – A (H) 1:320
SALMONELLA PARATYPHI – B (H) NO AGGLUTINATION
Fever with cough and phlegm, headache and too much body pain (lower body)
SALMONELLA TYPHI – O 1:320
SALMONELLA TYPHI – H 1:320
SALMONELLA PARATYPHI – A (H) 1:320
SALMONELLA PARATYPHI – B (H) NO AGGLUTINATION
Widal test is positive for enteric fever. This picture shows mixed infection. It would help if you had good antibiotics and avoid solid foods. Try to take a liquid diet.
In Above Typhi H is 1:320 does it mean patient has gained immunuty against bacteria? And now need to only focus on Paratyphi removal?
Typhi H rises late and disappears late. This antibody is against the flagellar antigen. In comparison, an antibody against O antigen appears early and disappears early.
My S. Typhi O titre= 1:160
And have fever since 4 days with wet cough, chills
What does thi mean please help
This titer of 1:160 indicates typhoid fever. You need treatment for typhoid fever.
Good day sir my report test says
Sal tyhi O:D1/20. H1/20
Salm paraty O:A1/40 H 1/20
Salm paraty O:B1/80 H 1/20
Salm paraty O: 1/80 H 1/40
Salmonella typhi is in the normal range. Paratyphi 1:80 is borderline. Please repeat after 5 to 7 days; if it increases, it is paratyphoid. If it is the same or decreased, then this test is negative.
plz save my mother sir,
my mother survive to widal daises , she is very seriously condition today,
plz sir, tell me, what can i do for my mother..
It looks that the widal test was positive. Please give her good antibiotics; if she is not improving, change the antibiotics.
Hi sir, my mother widal test result:
O – 1:80
H – 1:40
AH – 1:20
BH – 1:20
Method: rapid slide test
Please let me in know your advise
Salmonella O 1:80 is borderline, while others are negative. Please repeat the test after 5 to 7 days; if O is the same or less than 1:80, take it as a negative widal test.
Thank you For the reply sir
Thanks.
Aoa Sir my results are:
Typh O…1:80
Typh H…1:40
Typh AO…1:20
Typh AH…1:20
Typh BO…1:20
Typh BH…1:20
Is it typhoid??
Except Typhi O 1:80 is borderline, while all other titers are negative. Please repeat widal after 5 to 7 days. If O is again 1:80, then Widal is negative, and if it is 1:160 or more, that indicates typhoid fever.
Hi sir,
My 5Yr old son Widal test report says
Salmonella typhi 0 – 1:160
Salmonella typhi H – 1:160
Salmonella paratyphi AH – less than 1:20
Salmonella paratyphi BH – less than 1:20
Method : tube agglutination
Previously he was diagnosed with TYPHOID 5 months back
This widal test favors the diagnosis of typhoid fever. When this attack is over, I will suggest giving him a yearly vaccine for typhoid fever.
Please I don’t understand my test result. I need your help. It reads:
O. H
S. Typhi. 1/40. 1/40
S.paratyhi A 1/80. 1/40
S.paratyhi B. 1/80. 1/40
S.paratyhi. C. 1/80. 1/80
Widal reaction- positive rxu
1/80 for oAg.
S.Paratyphi 1:80 is borderline; you must repeat the widal test after 5 to 7 days. If this titer becomes 1:160, definitely enteric fever; if it remains the same or has lower values, then the widal test is negative.
My test results on day 3rd March were
Salmonella tirphi ‘O’ 1:80
Salmonella typhi ‘H’ 1:80
Salrnonella paratvphi’AH’ 1:20
Salmonellaparatyphi ‘BH’ : 1:320
I have no fever , no diarrhoea no symptoms of disease
last fever I got was in December which was treated
I have started by antibiotics yestarday
How long will it take me to get cured?
Salmonella BH 1:320 indicates past infection. Typhi 1:80 is borderline. Repeat widal after 5 to 7 days. If the same value, then typhoid fever is not possible.
Repeated the test today
Salmonella typhi O= 1:20
Salmonella typhi H= 1:20
Salmonella typhi AH = 1:20
Salmonella typhi BH = 1:320
I need to take Thypoid vaccine In this week for my intership In nestle production unit.
Can i take the vaccine or I have to wait?
Please I don’t understand my result.I need your help sir.Salmonella “O” Titre is 1: 180,Salmonella “H” Titre is 1: 80 and Lymphocytes is also low(17.7%). Then the widal test slide method is positive. Is this typhoid fever
And also having body pains, headache,cough, cold, throat pain. Previously two weeks back I got fever and it suffers one week and now also I got fever.
You can have a workup like a complete blood examination including ESR, X-Ray chest, and widal test.
Can i take Typhoid vaccine while typhoid my widal test Report are
Salmonella typhi O= 1:20
Salmonella typhi H= 1:20
Salmonella typhi AH = 1:20
Salmonella typhi BH = 1:320
Will there be side effect of the typhoid vaccine ?
In your widal test, BH = 1:320, which indicates past infection. Typhoid fever vaccination is given every year, so I think you can get the vaccination.
hello
can you please help me interpret these results:
Brucella abortis >1/360
Brucella melitensis >1/360
Widal (TH) 1/20
Widal (TO) 1/20
Widal (AH) 1/20
Widal (BH) 1/20
This test represents Brucellosis, and it is negative for typhoid fever.
Please Dr. I need explanation for my result
Widal test styphi o 1:260 s. Typhi h 1:80
Thus my result whsy treatment do i need for this
Please help me.
O 1:260 indicates typhoid fever. (These figures are usually as 1:80, 1:160, 1:320). This figure is strange for me as 1:260. But anyhow is positive for typhoid fever.
Hello Sir,
My husband’s Widal test report is:
WIDAL TEST, SERUM
(Slide Agglutination)
Salmonella typhi O (TO) Reactive upto Titre
– 1:80
Salmonella typhi H (TH) Reactive upto Titre
– 1:40
Salmonella paratyphi A, H (AH) – Non Reactive
Salmonella paratyphi B, H (BH) – Non Reactive
Please suggest what should we do now.
Regards
Archana
Salmonella O 1:80 is borderline. Please repeat the Widal test after 5 to 7 days, and if it is 1:160 or more, indicate typhoid fever. If it is the same or less, typhoid fever is ruled out. You can keep 24 hours temperature chart and pulse record.
Thank you Sir!
Hi sir
My widal test report below
S. Typhi O 1:320
S. Typhi h 1:160
S. Paratyphi A Negative
S. Paratyphi b Negative
Sir please confirm the results?
Is this positive or negative
This widal test is positive for typhoid fever. S. Typhi O 1:320 is quite a high titer for the diagnosis of typhoid fever. Needs treatment.
Also, Fever remained for few days which is fine now. But having cough from last few days and felt weakness . Secondly have Done ppd test. The tested area shows only redness. No bump or hardness felt. Sir please help me out. What does this indicates?
Hello Sir,
My husband’s Widal test report is:
Salmonella typhi O (TO) Reactive upto Titre – 1:80
Salmonella typhi H (TH) Reactive upto Titre – 1:40
As per your directions, I’m measuring his body temperature and pulse rate.
The temperature stays around 99.0-99.5°F and pulse rate stays around 60.
It has been 9 days since he got fever for the first time which was 101°F.
We’ve given sample for blood culture and the report is still awaited.
Please suggest what should we do now.
Regards
Archana
Widal S.typhi O 1:80 titer is borderline. Pulse 60/minutes is in the normal range. Fever is low grade. Have you checked his complete blood count with ESR? Does he have any symptoms, or does only the thermometer shows 99.0 F?
Hello Sir,
Thanks for replying.
My husband’s ESR is 14.
He got diarrhoea for a couple of days in between. But it’s better now.
He feels weak/tired and sometimes gets little headache as well.
He has got blister in mouth since 2 days.
Is there any way I can email you his test reports.
Also, he is diabetic and takes medication (Glucobay M50) twice a day. His gall bladder has been removed due to stones around 3.5 years ago.
Sir,
There is a lot of subjective variation in interpretation of WIDAL slide test. Is there any criteria or guideline for standard interpretation of WIDAL..????
The Widal test interpretations:
The titer of the antibody Interpretations of the Widal test
O-antigen = >1:160 Active infection
H-antigen = >1:160 Past infection or immunized
Rising titer = 1:40 to 1:80 to 1:160 Diagnostic
I think the above table gives an idea about the positive widal test.
Sir please check my nephew’s report
S Thypi O and H 1:>320
S Parathypi A 1:> 160
S Parathypi B 1:>80
This widal test is positive for typhoid fever. Needs treatment. Please advise complete blood picture and record temperature four hourly with a pulse.
Sir, If S typhi H is < 1:160 (1:40, 1:80) while S typhi O is less than 1:80, is it still considered past infection?
You need to repeat the test to see the typhi O titer. If it increases, then acute infection remains the same, then past infection.
Sir I did a widal test and the result is
Typhi D : O – 1/40, H – 1/40
Paratyphi A : O – 1/40, H – 1/40
Paratyphi B : O – 1/40, H – 1/40
Paratyphi C : O – 1/160, H – 1/80
Sir please is the result positive or negative?
S. Paratyphi C O 1:160 indicates Paratyphi fever. This widal test is positive.
What are the clinical significance of an increased in terms of the following antigen:
Vi
K
OXK
OX2
OX19
Vi antigen is virulence antigen. K antigen is a capsule that covers the O antigen. The Proteus suspension of OXK, OX2, and OX19 is used to diagnose rickettsial antibodies.

Good morning sir, i live in Nigeria
My widal results show:
O H
Salmonella Typhi (D)1/20 1/160
Salmonella Para Typhi (A) 1/20 1/80
Salmonella Para Typhi (B) 1/20 1/80
Salmonella Para Typhi (C) 1/80 1/40
The lab scientist says the significant titre is 1/80
IS it possibly a typhoid infection?
Keep up the good work.
The titer of 1:80 is borderline. You have to repeat the widal test after 5 to 7 days. If the titer rises to 1:160 or above, then definitely positive; if it is the same or decreasing level, then negative.
Hello Doctor, Good evening,
I had covid in jan,
Does this impact in widal test ?
As on 27th June,
S Typhi O – positive 1:80 dilution (slide)
S Typhi H – positive 1:80 dilution ( slide)
S para Typhi AH – negative 1:20 dilution(slide)
S para Typhi BH – negative 1:20 dilution (slide)
I had typhoid in my 10 years and now I am 33. Can I be the carrier of typhoid often? As my doctor said it may be.. what is the readings says..please guide..
Your widal is borderline. Please repeat widal after one week; if the titer is increased to 1:160 or more, then widal will be called positive. If the titer is the same at 1:80 or below, I will call the widal test negative. For the carrier, we advise Vi antigen.

Please help me explain… just wanna know if it’s positive and severe. I had this test done yesterday.
Thanks
Your titer S. Paratyphi B is 1:160, which indicates a positive widal test. It means you need treatment for paratyphoid.
THANKS DOC 🙏🤲
Hello doc.. Good Evening please I’m waiting for your response please 🥺
Hello doc,
I got this result Widal S. par B-H 1/160 and Widal S. par C-H 1/320.
Would these be previous para typhi?
Eosinophil is 9.8 btw
Eosinophils 9.8% indicate an allergy. It has no relation to typhoid fever. The best option is to deworm her. For low-grade fever, there are so many causes. It would be a better option to show her to a physician.
And my housemaid got this Widal S Typhi H 1/1280.
The last typhoid fever vaccination was in 2017. Could that be a reason why it’s this high? All the other are low or negative, but there is 38.8 fever though.
The titer of S Typhi-H indicates past infection or vaccination. The titer of S Typhi-O indicates acute infection.
Thank you, doc; I appreciate your dedication.
Thanks.
Doc, what are your thoughts on this?
In Indonesia, typhoid is prevalent. I see that the few people I’ve sent for a typhoid test have Titer Typhi O or par Typhi O 1/160. No fever or other symptoms; after repeating the test a week later, the titer is still 1/160.
Could it be possible that they don’t have typhoid since the titer didn’t go up, and 1/160 instead of 1/80 is borderline for them? Or maybe they’ve built up some resistance to typhoid?
The rising titer is essential for the diagnosis of active disease. If the titer is the same, in that case, the widal test is negative. Please ignore the titer of 1:160 when there are no signs and symptoms. In the prevalent areas, vaccination should be done for all.
“In the prevalent areas, vaccination should be done for all.” I’ll try to contact the government. No high hopes though 😀
Thank you doc. I am really happy with the info on this website. It’s easy to understand and that you are willing to answer questions is unique. A very welcome initiative.
Please sir, help me understand this result.

Kindly let me know, how severe is this.
Thanks in advance
The widal test is positive, so you need to treat the patient. The widal test does not indicate the severity of the disease.
Hi Sir,
I hope everything is going well for you all.

If typhi O is <1:80 and paratyphoid also <1:80, it does not favor typhoid fever.
Hi Dr,
I have night sweats from past 5 days .with fever of 98 to 99 but my body is hot to touch.with neck and shoulder pains
I had severe stress due to the same.
My WBC is 12500 and my widal results are o: 1/80
And H 1/160.
I was suggested by my doctor to start typhoid treatment. As many people in our locality are suffering with typhoid and even from my home.
Is my high WBC is something to do with stress or typhoid
Adding to above …I came to know that H tier 1/160 means recent typhoid infection..but I never had typhoid earlier or atleast from past 15 years and never took medication for the same .
You are right H titer indicates past infection or vaccination. But this will start appearing in the acute phase as well. The titer of the O antigen indicates acute infection.
Raised TLC is usually not seen in typhoid infections. In typhoid infection, TLS is low. The best option is to repeat the widal test after 5 to 7 days. If the O antigen’s titer is increased, it will indicate typhoid infection. If it is the same, then the possibility of typhoid infection is less likely.
S paratyphi AO 1:20
S paratyphi AH 1:20
S paratyphi BO 1:80
S paratyphi BH 1:80
S paratyphi CO 1:20
S paratyphi CH 1:160
S typhi DO 1:80
S typhi DH 1:160
Sir pls I need your interpretation and drug prescription.
This widal test is borderline. It needs to repeat after 7 days; if the Typhi O titer is increased, it is typhoid fever.
You have not given the history of fever and Total white cell count. If there is low TLC, that may favor typhoid fever. As regards medicine, please get in touch with your physician.
Sir, all results negative except typh H=1:160, is that means I’m typoid fever or the result was caused by vaccinated?
Sir, all results negative except typh H=1:160, is that means I’m typoid fever or the result was caused by vaccinated?
TYphi H indicates vaccination or past infection.
Thank you Dr
Hi Doctor,
2 weeks before i was diagnosed with Typoid and dengue NS1 positive. The doctor gave me medication.
I took blood test again after 2 weeks today and ended up with the below results.
S.TYPHI “O” Positive 1 in 80 dilution.
S.TYPHI “H” Negative 1 in 20 dilution.
S.PARATYPHI “AH” Negative 1 in 20 dilution.
S.PARATYPHI “BH” Negative 1 in 20 dilution
Am I having typhoid still? Do I need to continue taking medicine? Do I need to follow the oilless diet? Can I eat non veg?
Please help me on this query. Thank you🙏🏾
Typhi O titer 1:80 is borderline. Other all titers are normal. If you are taking medications for typhoid fever, please get your doctor’s advice. I think you need to continue a special diet for typhoid fever. Because intestines take time to heal, at least 4 weeks.
Hi Doctor, Thank you so much for the clear information. I appreciate your time and patience to reply to us. Thanks again 😊🙏🏾
You are welcome.
Sir
I am fed up typhoid. I had high fever before few years and got admitted in hospital…got many test including blood culture…all test negative. In discharge card they mentioned typhoid. Since then I have heard ache and pain in legs. Got detected with typhoid atleast 10 times in last 3 years. Mostly both O and H titre value is 1:120…am I a carrier…how to get tested for that? And does vaccination works for carrier? How to get rid of this?
For to confirm the carrier status, you have to do Vi antigen. In the case of a chronic carrier, you need antibiotics for a longer period. After the treatment, get a vaccination every year. Antibiotics can be advised by physicians.
thank you for your valuable information..
Welcome.
Hello Dr. Firstly, thankyou for explaining Widal and Typhi-dot tests in such an elucidate manner. My current report of Widal after 5 days of fever shows
O – 1:160
H- non reactive
My symptoms are high fever, stomach ache, stomach cramps, vomiting, nausea, headache, cough.
One of our Dr friend said that since H is non reactive, my report is negative and it shows past infection. Could you guide us please.
The O antigen is essential for diagnosing typhoid fever, and it is 1:160 indicating typhoid fever. You should consult a physician for the treatment of typhoid fever. H antigen is not important for the diagnosis of acute typhoid fever.
Thankyou so much.
Hello Doc.,
I would like to ask a question regarding, what are the clinical significance of the rise in titers of the following antigen:
A
B
Vi
K
OxK
Ox2
These are abbreviations of Paratyphi A, Paratyphi B, and Vi (virulence antigen). OXK is the proteus OXK antigens. K antigens are most likely is from blood group system.
These are an abbreviation of paratyphi A, B, and Vi indicates virulence antigen. OXK and OX2 are proteus antigens. K antigen belongs to blood group ABO system.
Good Evening Dr.,
I just got back my widal test results.
Salmonella typhi O: 1/180
Salmonella typhi H: 1/180
Salmonella paratyphi BO: 1/320
Salmonella paratyphi BH: 1/80
Salmonella paratyphi BO: 1/40
I wanted to know if I’m in the earlier stage of infection or later stage.
Will this go away without antibiotic treatment?
I do not think you need to wait for the treatment. Because Salmonella Paratyphi BO = 1:320. is enough evidence for the paratyphoid fever.
My Widel test result is
S. Typhi “H” : 1.60
S. Typhi “O” : 1.60
S. Typhi “AH” : Nil
S. Typhi “BH” : Nil
I had taken medicine for one week some 30 days ago. should I go for treatment agian?
If you do not have fever, then I do not think you should take antibiotics. O-antigen will disappear in around one year and H-antigen will take longer time to disappear from the blood circulation.
Good day Dr Riaz
Sir, I just got my result Widal shown:
Typhi H: 1/320
Typhi O: 1/320
What does it means?? Is it so serious to worry about?
Thank you for help.
Widal test is positive. Typhi O 1:320 indicate typhoid fever. You definitely need treatment for enteric fever.
Hello dr. Diaz thanks for your replies,
my wife report is S typhi O 1:40 H 1:160
S paratyphi A 1:00 1:140
as i read from your comments H is past infection and O is active infection,
her doctor gave her antibiotics for 5 days she has finished the cure tomorrow.
can we have intimate time togheder? or shoul she do the stool culture before we sleep togheder?
iam european she is from africa i did vivotif vaccine 2 months ago, if next whidal test come out with decreased value is still mandatory to do stool culture to see if i can be infected ?
best regards
I think you can have typhoid vaccination as a preventive measure.
i make a mistake i correct myself about S paratyphi A
O 1:00 H 1:40
Thanks in advance
Hi sir,
Recently 20days back I went for widal test due to symptoms I got.
O- 1:80
H-1:40
And I took medicine and recovered,after 2 weeks again I got viral fever ,cough and cold.
Again I given samples for cbp and widal test.
Report given me
O- 1:80
H- 1:80
Is it means do I still have typhoid? As I don’t have any symptoms even not fever.
Please help me sir.
Your titer of O = 1:80 same. So, it does not Favour typhoid.
Good afternoon Dr. Riaz,
I have following results but no symptoms. I have an active vaccination. The doctors gave me antibiotics. Do you think is correct to take them? I’m wondering how it is possible not to have symptoms.
S. Typhi “O” 1:320 positive
S. Typhi “H” 1:160 positive
S. Parathypi “A” 1:20 positive
S. Parathypi “B” negative
Thank you for the help in advance!

S. Parathypi “A” 1:20 positive
S. Parathypi “B” negative
Thank you for your advice in advance!
S Typhi O = 1:320 indicates typhoid fever and needs treatment. If you have no fever and no S/S, then repeat test from some other lab.
On first widal test O = 320 and H = 160
Taken antibiotics for 7 days
After 20 days again done widal test O = 320 and H = 320
Again after 7 days test O = 320 and H = 320
My doctor said no increase in titer it means negative now but still low grade fever
Salmonella O will be normal in a year time and H take more time to become low. If you do not have fever that is very important.
Sir My husband’s Widal Test Report is
Salmonella Typhi O (TO) =1.80
Salmonella Typhi H (TH) =1.80
Salmonella Paratyphi A (H) =1.40
Salmonella Paratyphi B (H) =1.40
is it positive andif yes, inhow many days it can be cured and what food can be taken to reduce typhoid
This widal test is borderline. If he has fever and bradycardia then repeat the test after one week. The titer will go up. Salmonella paratyphi is negative. Only salmonella typhi O 1:80 needs to be tested again. Please also check complete blood. That will also help to diagnose typhoid fever.
Dear Dr Riaz,
My medical attendant had typhoid. He was cured ultimately.
I had read that while they are free from the infection, they can be carriers for quiyte some time and should not be employed in Medical / food jobs.
I asked him to get a fresh Widal test 2 weeks after he was declared fit. The report was:
S TYPHI “O” 1:40
S TYPHI “H” 1:40
S PARA TYPHI A (H) – 1: 20
S PARA TYPHI B (H) – 1: 20
Can I re-employ him. He handles my medicines, serves food etc.
No doubt Widal test is negative. For carrier you have to check V1-antigen. If that is negative, then it is fine, and he can handle medicines and food.
Thank you for your prompt and excellent advice.
Hi my Dear Sir,
My son’s age is 6.5 years. Before 22 days he meets with a doctor for fever and cold problem. Doctor advise Moxaclav 125mg/5ml for seven days with some cold medicine. After seven days he got fine. But after two weeks fever again come with cold into breast. First day evening his eye was some red and headach. After five days we examine Febrile Antigen/ Triple Antigen Test and get the result TO 1:80, TH 1:80, AO 1:80, AH 1:80, BO 1:80, BH 1:80, Proteus OXK 1:80, Proteus OX2 1:160, Proteus OX19 1:80, B.abortus 1:80, B.mellitensis 1:80. All unit are Titre. Please give me a suggestion. I am waiting for your valuable reply.
All these titers are borderline, except for Proteus OX 1:160 which is positive. Please advise blood complete examination, that may be helpful. Next you can get blood culture, if he is not on antibiotics.
Dear my beloved Sir
Thank you for your prompt and excellent advice.
I also have done CBC, Urine R/E, Urine C/S and Blood C/S on same day but Urine C/S and Blood C/S report not yet get. Following is CBC Report : HB 11.6, ESR 19, WBC 5900, RBC 5.22, PC 265000, TEC 177, HCT 35.8 and other are in normal range.
Following are Urine R/E : color – straw, specific gravity – 1.003, appearance – clear, sediment – nil, blood – present, PH- 6.5, Urobilinogen – absent, Epithelial cells – 1-3/HPF, Pus cells 0-2/HPF, RBC 0-2 others some are nil and others some are absent.
Please give me your valuable suggestion. One more question is – “Is it an early step for doing such test after five days of fever?”
ESR is normal, so I do not think there is any serious issue. TLC indicates viral infection or normal in range.
I think your kid will recover soon. Wait for the culture reports.
Dear Dir
Thank you for valuable information.
We called a doctor and she gave an antibiotic azithomycine (Zithrin) for seven days @7.5 ml once a day.
After two days we already received culture report.
Blood culture report is : Culture incubated aerobically at 37°C for 72 hours has yielded No growth.
Urine culture report is : Culture incubated aerobically at 37°C for 48 hours has yielded No growth.
Both sample are given fifth day of fever.
Please give yor valuable suggestion. In urine r/e report blood is present
Urine and blood culture reports are negative. No need to worry. I hope your son will get well soon.
Dear my beloved Sir
I hope you are fine.
My son also fine now and antibiotic course (Azithromycin) end yesterday night.
Now I will share another problem of my same son which is noticed to us after two year of his birth. Now his age is 6.5 years. My baby’s upper part of penis was curled by birth, that is why his pee never full delivered and tha time we consult with doctor and he advise us to cut the upper part. we do the same work but his problem not solved yet. My son delivered pee frequently. First time he delivered sufficient pee without any problem but after 5 to 7 minutes he wants to pee again and the volume too much less then first time. some time he tell us his penis is burning during urination.
Please give your valuable advise. It will be more helpful to take decision for treatment.
Please consult pediatric urologist or surgeon. He needs plastic surgery and best person is pediatric urologist/surgeon.
NO doubt that titer of O is increasing, which indicate infection. Please let me know why you are doing widal test. Do you have fever?
I have replied your question.
Good morning sir,
Here is my widal test, I repeat it twice after 7days each but result is the same.
My question is do I have typhoid?
And I need I advice from you sir.
Thank you
O antigen salmonella typhi. 1:80
O antigen salmonella paratyphi a. 1:80
O antigen salmonella paratyphi b. 1:80
O antigen salmonella paratyphi c. 1:80

H antigen salmonella paratyphi a. 1:80
H antigen salmonella paratyphi b. 1:40
H antigen salmonella paratyphi c. 1:40
IF the titer is same, then widal test will be considered negative.
Dr., would you please reply about below result. What should I do? Test performed for my 2.5 yrs. old boy.
TO, AO, BO, TH, AH, BH of Widal test is 1:80
Proteus OXK, Proteus OX2, Proteus OX19 of Weil Felix Reaction is 1:80
Also 1:80 for Brucella Abortus, Br. Melitensis test.
Rising titer is more important. Please repeat after one week. if the titer is same, then I will take it negative. If there is increase in the titer of any of these, will indicate specific infection.

Sample Type -Serum
This Widal test is negative. There is possibility of past infection or vaccination.
Sorry Sir I forgot it .sir my ESR level was very high due to which there is pain in the whole body. All other tests are normal. So will you suggest any medicine to reduce ESR? Or how to reduce ESR. My ESR LEVEL is 39.
ESR is slightly raised, please repeat ESR after one month. If still raised then please consult physician to find the cause. You have not mentioned the age?
40 YEARS SIR
Sir i m 40 years old.Sir, I showed you my Widal test report on 10th July. So you said that the Widal test is negative. There is possibility of past infection. But I forgot to mention ESR. And you are telling that ESR is SLIGHTLY RAISED. And after 1 month you are saying ESR TEST. So sir, should I get WIDAL TEST done also. Because you said WIDAL TEST NEGATIVE but also said PAST INFECTION. So please tell me what? I should get WIDAL done along with ESR.Please guide me sir S’TYPHI

Still typhi H is 1:160, indicates past infection or vaccination. Otherwise Widal test is negative. You can get ESR, if it is normal, then relax. I do not think to repeat Widal test.
Dear sir,
with s.typhi o negative,
and s.typhi h 1:160 positive and no clincal features suggestive of infection- what needs to be done.
and especially people involved in catering industry how do we proceed about treatment and fit to work ?
S Typhi H = 1:160 indicates past infection or vaccination. For carriers you have to do Vi-antigen. If that is positive, then those carriers need long term antibiotics or cholecystectomy.
sir my ESR level was very high due to which there is pain in the whole body. All other tests are normal. So will you suggest any medicine to reduce ESR? Or how to reduce ESR. My ESR LEVEL is 39.
