CEREBROSPINAL FLUID (CSF) EXAMINATION

Overview

Cerebrospinal fluid (CSF) is a clear liquid that cushions the brain and spine, with a normal volume of 90-200 mL in adults. A CSF examination helps diagnose infections like meningitis, autoimmune disorders such as Guillain-Barré Syndrome and MS, and brain conditions like tumors or bleeding. Tests assess white blood cells, proteins, and bacteria in the CSF to identify these conditions.
