Abstract:
BACKGROUND:Visual assessment of cerebrospinal fluid (CSF) for xanthochromia (yellow color) is practiced by the majority of laboratories worldwide as a means of diagnosing intracranical bleeds. METHODS:Colorimetric and spectrophotometric analysis of CSF samples for recognizing the presence of bilirubin either in low concentrations or in the presence of hemolysed blood. RESULTS:The experiments provide the physiological and colorimetric basis for abandoning visual assessment of CSF for xanthochromia. CONCLUSIONS:We strongly recommend relying on spectrophotometry as the analytical method of choice.
