Summary

This study evaluates a rapid viability test for tuberculosis bacteria in sputum samples. The goal is to see if this test can accurately tell whether a patient is still contagious, compared to the standard culture method that takes weeks. If the test works, it could help doctors decide when it is safe to end isolation for hospitalized TB patients. The study includes 125 adults with smear-positive pulmonary TB who are already on treatment.
