Pathophysiology of Cerebrospinal fluid Xanthochromia

1. The normal color of the C S F is clear and colorless.
2. The color appearance depends upon the presence of hyperbilirubinemia, hypercarotenemia,  melanoma, and elevated protein level.
3. A cloudy appearance indicates an increased number of WBC or increased proteins.
4. A red tinge indicates blood that may be due to hemorrhage in the subarachnoid space or due to a traumatic tap.
5. Due to traumatic tap, blood may form clots, which will not occur in the subarachnoid bleeding.
