Diagnostic Accuracy of BD MAX MDR-TB Assay Performed on Bronchoscopy Specimens in Patients with Suspected Pulmonary Tuberculosis

Several novel molecular platforms using nucleic acid amplification tests have been developed for the diagnosis of pulmonary tuberculosis (PTB) and rapid detection of isoniazid and rifampin resistance. Among them, the BD MAX MDR-TB assay (BD MAX) has shown high sensitivity and specificity; however, its diagnostic accuracy performed on bronchoscopy specimens has not been reported.
