Signature Mapping TBDx: Created by the Aurum Institute, a South African health NGO, imaging specialists Guardian Technologies International, and South Africa’s national health laboratory services, the TBDx diagnostic system takes digital pictures of sputum samples and searches them for TB’s structural “fingerprint.”
In much the same way that airport x-ray machines detect bombs, TBDx uses digital microscopes to detect TB microbes by their shape. After positive results from initial testing in the national health laboratory services, the system is now in the final stages of an independently controlled clinical study in South Africa. Results are expected in April 2011 and tests are expected to cost around $5 each.
