严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的分子检测是准确诊断SARS-CoV-2感染的主要手段,但现有的检测方法的诊断性能尚未确定。我们比较了12种分子诊断方法,其中包括8种商业试剂盒,使用了从两家日本医院收集的155份呼吸道样本(65份鼻咽拭子,45份口咽拭子和45份痰)。有68份样本在一项以上检测和一个遗传座位上呈阳性,被定义为真阳性样本。所有检测方法的特异度均为100%(95%CI,95.8%~100%)。美国疾病预防控制中心的N_2试剂盒和日本国立传染病研究所的N_2试剂盒敏感性最高(95%CI,94.7~100),其次是美国疾病预防控制中心的N_1试剂盒、Corman的E试剂盒和日本国立传染病研究所的N_2试剂盒。当与适当的内控反应相结合时,这些分析作为实验室的一线分子分析是可靠的。
Molecular testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the mainstay for accurate diagnosis of the infection, but the diagnostic performances of available assays have not been defined. We compared 12 molecular diagnostic assays, including 8 commercial kits using 155 respiratory samples (65 nasopharyngeal swabs, 45 oropharyngeal swabs, and 45 sputum) collected at two Japanese hospitals. Sixty-eight samples were positive for more than one assay and one genetic locus, and were defined as true-positive samples. All the assays showed a specificity of 100% (95% CI, 95.8%–100%). The N2 assay kit of the US Centers for Disease Control and Prevention and the N2 assay of the Japanese National Institute of Infectious Disease (NIID) were the most sensitive assays with 100% sensitivity (95% CI, 94.7–100), followed by the Centers for Disease Control and Prevention N1 kit, E assay by Corman, and Japanese National Institute of Infectious Disease N2 assay multiplex with internal control reactions. These assays are reliable as first-line molecular assays in laboratories when combined with appropriate internal control reactions.
