Lessons Learned from Early Implementation and Scale-up of Stool-Based Xpert Testing to Diagnose Tuberculosis in Children
In 2020, fecal (stool) testing was recommended for diagnosing Mycobacterium tuberculosis complex (MTBC) infection in children by using the Cepheid Xpert MTB/RIF assay; since then, countries have begun implementing stool-based testing, often as part of a comprehensive strategy to enhance TB case fin...

| Summary: | In 2020, fecal (stool) testing was recommended for diagnosing Mycobacterium tuberculosis complex (MTBC) infection in children by using the Cepheid Xpert MTB/RIF assay; since then, countries have begun implementing stool-based testing, often as part of a comprehensive strategy to enhance TB case finding among children. On the basis of an experience-sharing workshop in November 2023, we determined insights of 9 early-adopter countries. Across those countries, 71,757 children underwent stool testing over a combined period of 121 months, October 2020–September 2023. A total of 2,892 children were positive for MTBC, and rifampin resistance was confirmed for 43 stool samples. The overall yield of MTBC detection across the countries was 4.1% (range 1.1%–17.3%). Stool collection for Xpert testing was considered noninvasive and as easy as sputum testing. Stool-based testing can be integrated into peripheral healthcare levels as a routine test to increase bacteriologic confirmation among children with presumptive TB.
