The Cepheid Xpert MTB/RIF assay utilizes sputum or decontaminated and pelleted sputum sediment. Specimens are inoculated directly into single disposable test cartridge, which contains both DNA extraction and target amplification material. The assay amplifies a 192-bp segment of the rpoB gene for Mycobacterium tuberculosis complex identification as well as rifampin resistance profiling. The Cepheid Xpert MTB/RIF assay is a closed PCR system that greatly reduces the potential for false-positive results due to specimen cross-contamination as compared with traditional open-system PCR methods.(Package insert: Xpert MTB/RIF.
