Previously, we have tested the breath profile of a small number patients from local TB clinics and have confirmed the presence of these biomarkers in their breath (IRB_0065207). Larger patients studies are now required to gain an estimate of the sensitivity and specificity to determine the potential of using the sensor as a screening test. This study will be conducted in Mumbai, India with the University's Research Electronic Data Capture (REDCap) system used to securely collect and store the data from this study.
