The Xpert MTB/RIF assay is a rapid and fully automated real-time PCR assay. The performance of the Xpert MTB/RIF assay as a primary screening test for urgent clinical specimens was evaluated during a 2-year period. The results showed that replacing smear microscopy with the Xpert MTB/RIF assay facilitates laboratory handling and improves the sensitivity and specificity of Mycobacterium tuberculosis detection.
Xpert MTB/RIF assay 是一种快速且全自动的实时 PCR 检测方法。在为期两年的研究期间,评估了 Xpert MTB/RIF assay 作为紧急临床标本一线筛查检测的性能。结果表明,用 Xpert MTB/RIF assay 取代痰涂片显微镜检查,有利于实验室处理,并且提高了结核分枝杆菌检测的敏感性和特异性。
