LOINC description : A sample of cerebrospinal fluid (CSF) is collected using a procedure called a lumbar
puncture or spinal tap. Often, three or more separate tubes of CSF are collected (tube
1, tube 2, tube 3), and multiple tests may be run on the different tubes. Normal CSF
is clear and colorless. Changes in the color of the CSF are not diagnostic but may
point to additional substances in the fluid. Yellow, orange, or pink CSF may indicate
the breakdown of blood cells due to bleeding into the CSF or the presence of bilirubin.
Green CSF may also sometimes be seen with bilirubin or infection. [Lab Tests Online];
