AFB For Fluid

Description

This test is designed to detect the presence of acid-fast bacilli (AFB) in various body fluids, such as pleural fluid, cerebrospinal fluid, or ascitic fluid. It’s primarily used to diagnose extrapulmonary tuberculosis, which affects areas outside the lungs. The test involves staining the fluid sample and examining it under a microscope for the presence of acid-fast bacilli. While a positive result can indicate the presence of mycobacteria, including Mycobacterium tuberculosis, a negative result doesn’t rule out infection. This test is often used in conjunction with culture tests and molecular methods for a comprehensive diagnosis of mycobacterial infections in body fluids.
