Highly sensitive and specific nucleic acid amplification tests (NAATs) have emerged as the gold standard diagnostic tests for many infectious diseases. Real-time PCR has further refined the technology of nucleic acid amplification with detection in a closed system and enabled multiplexing to simultaneously detect multiple pathogens. It is a versatile, fast, and high-throughput system for pathogen detection that has reduced the risk of PCR contamination, eliminated post-PCR manipulations, and improved the cost-effectiveness of testing. In addition, real-time PCR can be applied to self-collected noninvasive specimens. Here, we describe an in-house developed TaqMan-based real-time multiplex PCR (M-PCR) assay for the diagnosis of sexually transmitted genital ulcer disease (GUD) and discuss briefly on issues associated with validation of assay performance.
高灵敏度和特异性的核酸扩增检测(NAATs)已成为许多传染病的金标准诊断检测方法。实时荧光定量聚合酶链反应(Real-time PCR)通过在封闭系统中进行检测,进一步完善了核酸扩增技术,并实现了多重检测,能够同时检测多种病原体。它是一种用于病原体检测的通用、快速且高通量的系统,降低了聚合酶链反应(PCR)污染的风险,省去了PCR后的操作,并提高了检测的成本效益。此外,实时荧光定量聚合酶链反应(Real-time PCR)可应用于自行采集的非侵入性标本。在此,我们描述了一种自行研发的基于TaqMan的实时荧光定量多重聚合酶链反应(M-PCR)检测方法,用于诊断性传播性生殖器溃疡疾病(GUD),并简要讨论了与检测性能验证相关的问题。
