Clinica Chimica Acta: IgA在SARS-CoV-2感染早期的作用?

2021-01-03 MedSci原创 MedSci原创

病毒基因组序列分析显示从中国武汉获得的肺炎患者呼吸道样本中分离出一种新型冠状病毒(SARS-CoV-2)。

病毒基因组序列分析显示从中国武汉获得的肺炎患者呼吸道样本中分离出一种新型冠状病毒(SARS-CoV-2)。抗体对SARS-CoV-2的反应尚不清楚,但敏感性和特异性的血清学分析的可用性将对感染的早期诊断、流行病学研究和确定中和抗体的存在,以及对可能出现的疫苗至关重要。

本研究测试并比较了一种化学发光免疫分析法(CLIA)、两种酶联免疫吸附法(ELISA)和一种电化学发光免疫分析法(ECLIA)的性能。

研究结果显示,ECLIA血清学检测效果最好,很可能是一种有效的筛查SARS-COV-2感染的方法。ELISA检测IgA可能是一种比IgM更可靠、更稳定的早期血清学标志物。与预期相反,IgGs在症状出现10天后表现仍稳定。

考虑到优良的性能和单次试验的成本,ECLIA方法可以作为筛选试验,而ELISA检测IgG和IgA水平高于IgM且持续时间较长,故可作为验证试验。
