Diabetes Mellitus:- Part 9 – Glucose Random (Diabetes mellitus)

Glucose Random

Random blood glucose is without any relation to time or food.
1. This is done out of your normal routine testing.
2. This is always a nonfasting sample.
Interpretation:
1. If it is above 200 mg/dL and the patient has increased thirst, polyuria, and polyphagia, the random blood glucose suggests diabetes mellitus.
2. As a rule, two-hour glucose samples will reach the fasting level or be in the normal range.
  Postprandial (glucose 2 hours) presentation

Random blood sample:
1. Before the meal is 80 to 120 mg/dl (4.4 to 6.6 mmol/L).
2. After the meal and if the person is awake, 100 to 140 mg/dl ( 5.5 to 7.7 mmol/L ).
3. At bedtime also maybe 100 to 140 mg/dl ( 5.5 to 7.7 mmol/L).
Normal Random glucose level between 80 to 140 mg/dL (4.4 to 7.8 mmol/L).
Reliability of random blood glucose: If it is above 200 mg/dL, it indicates diabetes.
The glucose level in various conditions

Interpretation of the fasting and random glucose level:

Fasting glucose level	Normal range and need advise
80 to 120 mg/dL	Normal range and no need for any action
120 to 160 mg/dL	Slightly high and needs medical advise
160 to 240 mg/dL	It is high and needs medical advice and treatment
240 to 300 mg/dL	Too high and needs medical advice and treatment
Random glucose level
80 to 14 mg/dL	Normal and no need for any action
140 to 200 mg/dL	It is high and needs medical advice
