CSF also removes waste products from the brain and helps your central nervous system work properly.A CSF analysis is a group of tests that look at your cerebrospinal fluid to help diagnose diseases and conditions that affect the brain and spinal cord.Other names: Spinal Fluid Analysis, CSF Analysis
