Impact of sputum quality on Xpert MTB/RIF Ultra test results for tuberculosis: A multi-country study

2026-04-03

Abstract excerpt

<h4>ABSTRACT</h4> <h4>Rationale</h4> Sputum-based testing using Xpert MTB/RIF Ultra (Xpert) is the most common molecular testing method for diagnosing tuberculosis (TB). <h4>Objectives</h4> To evaluate whether sputum quality influences Xpert positivity and diagnostic accuracy. <h4>Methods</h4> We screened consecutive people for presumptive TB in India, the Philippines, Vietnam, Nigeria, South Africa, Uganda, a...
