PCR is recognized as a reliable technique for detection of all types of microorganisms. Being highly objective and reproducible also sensitive and specific, PCR is now widely used for sexually transmitted infection (STI) diagnosis. Potential, however, exists for detecting non-pathogens, and not identifying a pathogenic state decreases specificity or clinical significance. PCR Candida tests of vaginal specimens are now widely available and frequently used offering a modest to moderate increase in sensitivity and are likely to replace traditional culture and DNA homology testing. Nevertheless, there remain considerable gaps in our knowledge regarding the usefulness and applications of these expensive tests.
PCR 被公认为一种可靠的技术,可用于检测所有类型的微生物。由于其具有高度客观性、可重复性、敏感性和特异性,PCR 现在已被广泛用于性传播感染(STI)的诊断。然而,PCR 检测也存在检测非病原体的可能性,而无法识别病原体状态会降低特异性或临床意义。目前,阴道标本的 PCR 假丝酵母菌检测已广泛应用并经常使用,其敏感性适度增加,可能会取代传统的培养和 DNA 同源性检测。然而,关于这些昂贵测试的有用性和应用,我们的知识仍然存在相当大的差距。
