目前有几种SARS-CoV-2 RT-PCR的商业检测方法,但其中很少进行了评估。我们使用41份鼻咽样本对Allplex 2019-nCoV (Seegene)检测进行了评估。与GeneFinder COVID-19 plus (Elitech)和传染病专家诊断的符合率分别为92.7%和100%。4个样本显示E和RdRp基因的Ct < 22.0,而N基因未检测到,表明病毒序列存在变异性。与其他呼吸道病毒无交叉反应。Allplex 2019-nCoV似乎是一种可靠的方法,但需要使用更多样本进行额外评估。RT-PCR检测应该包括至少2个病毒靶标。
Several commercial assays for SARS-CoV-2 RT-PCR are available but few of them were assessed. We evaluate the Allplex 2019-nCoV (Seegene) assay using 41 nasopharyngeal samples. The rates of agreement were 92.7% and 100% with the GeneFinder COVID-19 plus (Elitech) and the diagnosis of the infectious disease specialist respectively. Four samples display a Ct < 22.0 for the E and RdRp genes while the N gene was not detected, suggesting a variability of the viral sequence. There was no cross-reactivity with other respiratory viruses. The Allplex 2019-nCoV appears as a reliable method, but additional evaluations using more samples are needed. RT-PCR assays should probably include at least 2 viral targets.
