The Culture CSF (Aerobic) test is used to detect bacterial infections in the cerebrospinal fluid (CSF), the fluid surrounding the brain and spinal cord. This test involves collecting a sample of CSF through a lumbar puncture (spinal tap) and incubating it in an aerobic environment (with oxygen) to encourage the growth of any bacteria that may be present.

This test is crucial for diagnosing serious infections like bacterial meningitis or encephalitis , which can cause inflammation of the brain or spinal cord. By identifying the specific bacteria, the test helps guide appropriate antibiotic treatment, which is critical for managing these potentially life-threatening conditions.
