Multicenter Study Comparative StudyXpert MTB/RIF Ultra assay for the diagnosis of pulmonary tuberculosis in children: a multicentre comparative accuracy study.
We evaluated the diagnostic performance of the novel next-generation Xpert MTB/RIF Ultra (Xpert Ultra) in comparison to Xpert MTB/RIF (Xpert) assay for the detection of paediatric pulmonary tuberculosis in high burden settings. ⋯ Xpert Ultra was found to have a higher sensitivity, but slightly reduced specificity compared to Xpert in detecting pulmonary tuberculosis in children.
