We aim to develop and test the performance of a 2nd generation TB Color Plate test with the ultimate goal of developing and implementing a faster (14 vs. 56-84 days), field-based, easy-to-use, and inexpensive drug susceptibility testing (DST) for drug-resistant TB in high TB index rate regions. This will allow faster detection, cost reductions, and thus, significantly aid in preventing transmission of drug-resistant TB in humans.
