SARS-COV-2感染的快速检测是控制大流行的重要工具,但目前的快速检测基于专有设计和试剂。我们报告了使用市售材料和试剂,以及RT-qPCR和市售比较器(BinaxNOW®和Sofia®)的开放获取横向流动测定(OA-LFA)设计的临床验证结果。根据临床体征和症状,且症状持续时间≤7天的疑似COVID-19成年患者进行了鼻前(AN)采样,进行ova - lfa、Sofia®、BinaxNOW™和RT-qPCR,以及鼻咽(NP) RT-qPCR。结果表明,与NP抽样的预测一致性为69% (60% -78%)OA-LFA, 74% (64% - 82%) Sofia®和82% (73% - 88%)BinaxNOW™。这些结果的含义是,我们提供了一种开放获取的LFA设计,满足世卫组织快速检测的最低目标产品配置,几乎任何诊断制造商都可以生产。
Rapid tests for SARS-COV-2 infection are important tools for pandemic control, but current rapid tests are based on proprietary designs and reagents. We report clinical validation results of an open-access lateral flow assay (OA-LFA) design using commercially available materials and reagents, along with RT-qPCR and commercially available comparators (BinaxNOW® and Sofia®). Adult patients with suspected COVID-19 based on clinical signs and symptoms, and with symptoms ≤7 days duration, underwent anterior nares (AN) sampling for the OA-LFA, Sofia®, BinaxNOW ™, and RT-qPCR, along with nasopharyngeal (NP) RT-qPCR. Results indicate a positive predictive agreement with NP sampling as 69% (60% -78%) OA-LFA, 74% (64% - 82%) Sofia®, and 82% (73% - 88%) BinaxNOW™. The implication for these results is that we provide an open-access LFA design that meets the minimum WHO target product profile for a rapid test, that virtually any diagnostic manufacturer could produce.
