Study Overview
Brief Summary
Consenting adults presenting with signs and symptoms compatible with pulmonary tuberculosis will be interviewed for demographic and medical information, and then will be asked to provide 3-4 expectorated sputum specimens. In the study laboratory, sputa will be tested using conventional and investigational diagnostic tests for tuberculosis and rifampin resistance.
