ABSTRACT

The objective of this study to compare the result of AFB microscopy and CBNAAT test and determine the efficiency of detecting M. Tuberculosis by AFB microscopy and CBNAAT test and its impact on diagnosis of tuberculosis. The retrospective study conducted in Parul Sevashram Hospital. The total 50 sample collected for this study. Data on suspected extra pulmonary tuberculosis TB patients is collected from January 2021 to October 2021. This sample includes Lymph node, Plural fluid, Bald fluid, Pus, Tissue, abscess, synovial fluid, Ascitic fluid, CSF, Pleural effusion, Pericardial fluid. Out of 50 sample, 6 sample found AFB positive and 44 sample found negative. CBNAAT test conducted for same 50 sample, we found 20 out of 50 sample found CBNAAT positive and 30 sample found CBNAAT negative. After comparing AFB result with CBNAAT it is observe that total 14 AFB negative sample turn into positive in CBNAAT. The conclusion of this study is that CBNAAT is more effective and accurate than the AFB microscopy test for diagnosis of extra-pulmonary tuberculosis.

Key words: CBNAAT, AFB microscopy, Extra pulmonary tuberculosis, tissue, fluid.
