We evaluated the performance of a laboratory-developed multiplex real-time reverse transcription-PCR assay (LDT rRT-PCR), the Centers for Disease Control and Prevention (CDC) 2009 H1N1 rRT-PCR protocol using the LightCycler 480 II, the multiplex xTAG Respiratory Virus Panel (xTAG RVP), and rapid immunodiagnostic testing (RIDT) using the BinaxNOW Influenza A & B to detect 2009 H1N1 with 426 nasopharyngeal swab specimens during the 2009 H1N1 pandemic. The specificity of the methods tested was ≥98%, and the individual test sensitivities were RIDT at 42.3% [95% confidence interval (CI), 31.4-54.0], LDT rRT-PCR at 98.9% (95% CI, 92.9-99.9), CDC 2009 H1N1 rRT-PCR at 78.2% (95% CI, 67.8-86.0), and xTAG RVP at 93.1% (95% CI, 85.0-97.2). A negative RIDT result should not be used to make decisions with respect to treatment or infection prevention. rRT-PCR is the preferred first-line diagnostic test for detecting 2009 H1N1 influenza A.
我们评估了一种实验室开发的多重实时逆转录聚合酶链反应检测方法(LDT rRT-PCR)、疾病控制和预防中心(CDC)2009 年 H1N1 rRT-PCR 方案(使用 LightCycler 480 II)、多重 xTAG 呼吸道病毒检测试剂盒(xTAG RVP)以及快速免疫诊断检测(RIDT),使用 BinaxNOW 流感 A 和 B 检测试剂盒,共检测了 426 份鼻咽拭子标本,以在 2009 年 H1N1 大流行期间检测 2009 年 H1N1 病毒。方法的特异性均≥98%,单独检测的敏感性为 RIDT 为 42.3%(95%置信区间,31.4-54.0),LDT rRT-PCR 为 98.9%(95%置信区间,92.9-99.9),CDC 2009 年 H1N1 rRT-PCR 为 78.2%(95%置信区间,67.8-86.0),xTAG RVP 为 93.1%(95%置信区间,85.0-97.2)。RIDT 阴性结果不应用于治疗或感染预防决策。rRT-PCR 是检测 2009 年 H1N1 甲型流感的首选一线诊断检测方法。
