Diagnostic accuracy of tongue swab testing in persons with sputum Xpert Ultra Trace results

2025-07-16

Abstract excerpt

<h4>Background</h4> Molecular amplification of tongue swab samples is a non-sputum-based investigational approach to diagnose pulmonary tuberculosis (pTB). An improved manual qPCR method for tongue swabs recently achieved >90% sensitivity overall in diagnosing TB, compared to a sputum microbiologic reference standard. Performance characteristics in persons with low-positive results on sputum molecular tests are u...
