CSF C/S for AFB

The CSF C/S for AFB, or cerebrospinal fluid culture and sensitivity for acid-fast bacilli, is a diagnostic test used to detect the presence of tuberculosis bacteria in the fluid surrounding the brain and spinal cord. During the procedure, a sample of cerebrospinal fluid is collected through a lumbar puncture, and it is then cultured in a laboratory to identify any bacterial growth, specifically focusing on those that are acid-fast, which are indicative of tuberculosis. This test helps in diagnosing central nervous system infections and guiding appropriate treatment options.
