How do you test for cerebrospinal fluid?

This test is done to measure pressures within the CSF and to collect a sample of the fluid for further testing. CSF analysis can be used to diagnose certain neurologic disorders. These may include infections (such as meningitis) and brain or spinal cord damage.

What is cerebrospinal fluid and what color is it?

Color of the fluid — normal 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.

What structures produce CSF and where are they located?

There are cavities in your brain called ventricles. The structure located in the ventricles that produces cerebrospinal fluid is called the choroid plexus. The cerebrospinal fluid is a clear, protective fluid made by the cells of the choroid plexus, and it is commonly abbreviated CSF.
