Using data for 20 912 patients from 2 large academic health systems, we analyzed the frequency of severe acute respiratory syndrome coronavirus 2 reverse-transcription polymerase chain reaction test discordance among individuals initially testing negative by nasopharyngeal swab who were retested on clinical grounds within 7 days. The frequency of subsequent positivity within this window was 3.5% and was similar across institutions.
使用来自 2 个大型学术医疗系统的 20912 名患者的数据，我们分析了在最初通过鼻咽拭子检测为阴性的个体中，基于临床原因在 7 天内再次检测时出现严重急性呼吸综合征冠状病毒 2 逆转录聚合酶链反应检测不一致的频率。在此窗口期内后续检测呈阳性的频率为 3.5%，并且在各个机构之间相似。
