This study compares the detection of 14 common respiratory viruses by two different real-time reverse transcription polymerase chain reaction (rRT-PCR) methods: in house singleplex tests developed by the Centers for Disease Control and Prevention and the commercially available Fast Track Diagnostic (FTD®) Respiratory Pathogens 33 multiplex test.
A total of 217 nasopharyngeal swabs were analyzed using CDC singleplex rRT-PCR and FTD® Respiratory Pathogens 33 multiplex assays, for the detection of 14 respiratory viruses.
The results showed that 179/217 (82.5%) samples were positive with the singleplex method and 183/217 (84.3%) with the FTD® Respiratory Pathogens 33 multiplex test. Excellent or satisfactory agreement was obtained for all viruses (k > 0.6) except Parainfluenzavirus 4 (k = 0.24) and influenza B (k = 0.51).
Although the multiplex FTD kits were more expensive than the singleplex assay, the FTD kits yielded rapid results in a shorter timeframe, increasing efficiency of diagnosis.
本研究比较了两种不同的实时逆转录聚合酶链反应(rRT-PCR)方法对 14 种常见呼吸道病毒的检测效果:美国疾病控制与预防中心(CDC)开发的内部单重测试和市售的 Fast Track Diagnostic(FTD®)呼吸道病原体 33 多重测试。
使用 CDC 单重 rRT-PCR 和 FTD®呼吸道病原体 33 多重检测法对 217 份鼻咽拭子进行分析,以检测 14 种呼吸道病毒。
结果显示,179/217(82.5%)份样本用单重方法呈阳性,183/217(84.3%)份样本用 FTD®呼吸道病原体 33 多重检测法呈阳性。除副流感病毒 4(k=0.24)和乙型流感病毒(k=0.51)外,所有病毒(k>0.6)的一致性均为优秀或满意。
尽管 FTD 多重试剂盒比单重检测法昂贵,但 FTD 试剂盒在更短的时间内快速得出结果,提高了诊断效率。
