This pilot study will be conducted to determine if a newly developed sensing methodology for screening TB at the POC based on volatile biomarkers is feasible through the use of a low cost solid-state sensor using functionalized 3D TiO2 nanotube arrays that bind the volatile biomarkers. If the clinical sensitivity is sufficient, this technology could provide a means for identifying many of the 'missed' TB patients and allow testing resources and efforts to be focused on those at the highest risk of having the disease.
