Useful For
Xanthochromia is present in more than 90% of patients within 12 hours of a subarachnoid hemorrhage. It is defined as the yellow, orange, or pink discoloration of the CSF, most often caused by the lysis of RBCs resulting in hemoglobin breakdown to oxyhemoglobin, methemoglobin, and bilirubin. Discoloration begins after RBCs have been in spinal fluid for about 2 hours, and remains for 2 to 4 weeks.
