S01E38 | Portable TB Testing — MiniDock MTB and Diagnostic Equity

In this episode of PRISM Rounds, we review the NEJM study of MiniDock MTB, a portable near-point-of-care molecular test for pulmonary tuberculosis using sputum and tongue swabs.The study found that MiniDock MTB outperformed smear microscopy, approached Xpert Ultra performance with sputum swabs, and met WHO near-point-of-care diagnostic accuracy targets. We discuss why this matters for resource-limited settings, where delayed TB diagnosis, repeat visits, and limited access to molecular testing remain major barriers to care.We also cover the key limitations: lower sensitivity in paucibacillary disease, smear-negative TB, and people living with HIV, plus the need for reflex drug-resistance testing.Educational use only.
