Title: Feasibility and Accuracy of a Novel Xpert Cartridge for Rapid Molecular Detection of Drug Resistant Mycobacterium Tuberculosis in Sputum
Brief Summary: Consenting adults will be interviewed for demographic and medical information, and then will be asked to provide two expectorated sputum specimens. In the study laboratory, sputa will be tested using conventional and investigational diagnostic tests for tuberculosis.

    * Previously diagnosed with MDR-TB and failed TB treatment with positive sputum smear or culture after ≥3 months of a standard MDR-TB treatment regimen
