There were 90 patients with suspected tuberculosisin sputum-smear negative or less sputum. MGIT, Xpert and ZN of bronchoscopy bronchoscopic lavage. Results: MGIT assay against the standard with combined TB diagnosis had a sensitivity of 72.5%, a specificity of 71.4%, a positive predictive value of 89.3% and a negative predictive value 44,1%. The MGIT test against the Xpert standard for TB diagnosis had a sensitivity of 64.3%, a specificity of 82.4%, a positive predictive value of 85.7% and a negative predictive value of 58.3%.
