Rapid Diagnosis of Tuberculosis from Analysis of Urine Volatile Organic Compounds. ACS sensors Lim, S. H., Martino, R., Anikst, V., Xu, Z., Mix, S., Benjamin, R., Schub, H., Eiden, M., Rhodes, P. A., Banaei, N. 2016; 1 (7): 852-856

Abstract

The World Health Organization has called for simple, sensitive, and non-sputum diagnostics for tuberculosis. We report development of a urine tuberculosis test using a colorimetric sensor array (CSA). The sensor comprised of 73 different indicators captures high-dimensional, spatiotemporal signatures of volatile chemicals emitted by human urine samples. The sensor responses to 63 urine samples collected from 22 tuberculosis cases and 41 symptomatic controls were measured under five different urine test conditions. Basified testing condition yielded the best accuracy with 85.5% sensitivity and 79.5% specificity. The CSA urine assay offers desired features needed for tuberculosis diagnosis in endemic settings.
