Pleural tap was done and 20 ml of pleural fluid was sent to laboratory for ADA level and at the same time Abram's pleural biopsy was done from the same site.RESULTS: Mean age of the patients was 40.28±16.31 years. Gender distribution showed 62 patients (54.4%) were male while 52 patients (45.6%) were female. Pleural fluid adenosine deaminase (ADA) showed sensitivity (86.36%), specificity (61.54%), diagnostic accuracy (80.70%), positive predictive value (88.37%) and negative predictive value (82.42%) confirmed by pleural biopsy as a gold standard.CONCLUSION: It is concluded from this study that although Biopsy is the gold standard in diagnosing tuberculosis pleural effusion. ADA is cheap, readily available and non-invasive test that shows good diagnostic accuracy in tuberculosis pleural effusion. ER -
