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.
背景
全球大多数实验室都通过对脑脊液（CSF）进行黄变（黄色）的视觉评估来诊断颅内出血。
方法
采用比色法和分光光度法分析脑脊液样本，以识别低浓度胆红素或存在溶血血液时胆红素的存在情况。
结果
这些实验为放弃对脑脊液黄变的视觉评估提供了生理和比色学依据。
结论
我们强烈建议将分光光度法作为首选的分析方法。
