AFB Smear Examination by Fluorescent Stain, BAL / Respiratory sample

The "AFB-Smear examination by Fluorescent stain - BAL / Other Respiratory Sample" test is used to diagnose tuberculosis (TB) infection. This test's clinical utility lies in its ability to detect acid-fast bacilli (AFB), which are specific to the Mycobacterium tuberculosis bacterium responsible for causing TB, in respiratory samples such as bronchoalveolar lavage (BAL) or other respiratory specimens. The fluorescent stain used in the AFB-Smear examination allows for the visualization of AFB under a fluorescent microscope, making it easier to identify the presence of Mycobacterium tuberculosis. This rapid and direct examination method is a valuable initial step in diagnosing TB infection. If AFB are detected in the respiratory sample, further tests, such as culture and molecular tests, may be performed for confirmation and to determine drug sensitivity. Timely and accurate diagnosis through the AFB-Smear examination enables healthcare professionals to initiate appropriate treatment promptly, prevent the spread of TB, and improve patient outcomes. The test's clinical utility is vital in identifying and managing TB infections effectively, thus reducing the burden of the disease on both the individual and the community.
