The Culture Body Fluids (Aerobic) test is used to detect bacterial infections in body fluids (such as pleural, peritoneal, synovial, or cerebrospinal fluid) that are normally sterile. The test involves collecting a sample of the body fluid and incubating it in an aerobic environment (with oxygen) to allow any present bacteria to grow.

This test helps diagnose infections in body cavities or fluids that have become infected, such as peritonitis, septic arthritis, or infections related to the central nervous system or other organs. Identifying the specific bacteria present allows for targeted treatment with the appropriate antibiotics, improving the effectiveness of therapy and reducing the risk of complications.
