Use of Xpert^® MTB/RIF assay in the first national anti-tuberculosis drug resistance survey in Pakistan

Abstract

This survey provides the first representative data for Pakistan on its MDR-TB burden. The Xpert assay had nearly 100% specificity, even in a low MDR-TB prevalence setting. The use of this assay greatly simplifies survey logistics, making it a feasible option for survey implementation, especially in resource-constrained settings.
