This test may be done to diagnose tumors, infections, inflammation of the central nervous system, delirium, and other neurological and medical conditions.
How is the Test Performed?
A sample of CSF is needed. A lumbar puncture, also called a spinal tap, is the most common way to collect this sample. For information on this procedure, see the article on lumbar puncture.
Other methods for collecting CSF are rarely used, but may be recommended in some cases. They include: - Cisternal puncture
- Ventricular puncture
- Removal of CSF from a tube that is already in the CSF, such as a shunt or ventricular drain
After the sample is taken, it is sent to a laboratory for evaluatoin.
