Cerebrospinal fluid Xanthochromia , (CSF)
- Cerebrospinal fluid is needed.
- To assess the presence of protein in the C S F.
- The normal color of the C S F is clear and colorless.
- The color appearance depends upon the presence of hyperbilirubinemia, hypercarotenemia, melanoma, and elevated protein level.
- A cloudy appearance indicates an increased number of WBC or increased proteins.
- A red tinge indicates blood that may be due to hemorrhage in the subarachnoid space or due to a traumatic tap.
- Due to traumatic tap, blood may form clots, which will not occur in the subarachnoid bleeding.
- In traumatic tap, successive tubes become clear of blood.
- Xanthochromia is usually referred to as a yellow tinge.
How to check xanthochromia
- The easiest way is that centrifuge the CSF and sees it against the white background.
Xanthochromia, when positive in the CSF, indicates a raised level of protein.
