Now, diagnosing multi-drug resistant TB (MDR TB) patients will take less than two hours. India has cleared the proposal to roll out a new diagnostic test GeneXpert across 18 sites that will test and confirm MDR TB within 120 minutes. About 99,000 Indians suffering from TB are becoming drug resistant every year. However, the diagnostic tools available take two days to about four months to confirm a single drug-resistant case during which time the air-borne disease spreads to others. The new test aims to increase diagnosis of the disease by at least seven-fold.
