Abstract
An ultra-sensitive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid antigen assay (S-PLEX, MesoScale Diagnostics) was evaluated in 250 retrospective and 200 prospective upper respiratory specimens. In samples with cycle threshold <35, there was 95%-98% positive and 93%-96% negative percent agreement with reverse transcription-polymerase chain reaction. S-PLEX may provide a high-throughput alternative to nucleic acid-based testing for coronavirus disease 2019 (COVID-19) diagnosis.
摘要
一种超灵敏的严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）核衣壳抗原检测试剂盒（S-PLEX，MesoScale Diagnostics）对 250 份回顾性和 200 份前瞻性上呼吸道标本进行了评估。在循环阈值<35 的样本中，与逆转录-聚合酶链反应（RT-PCR）相比，该检测试剂盒的阳性符合率为 95%-98%，阴性符合率为 93%-96%。S-PLEX 可能为新型冠状病毒病（COVID-19）诊断提供一种高通量的核酸检测替代方法。
