New Test Approved to Quickly Detect Drug-Resistant TB

By the Editors

The FDA has approved the Xpert MTB/RIF Assay to detect active tuberculosis. The test can also identify whether the bacteria have genetic markers that confer resistance to rifampin.

Test results are generally available within 2 hours, as opposed to the 1 to 3 months it typically takes for traditional tests for drug-resistant TB.
