我们利用2个大型学术卫生系统的20912例患者的资料，分析了7天内经鼻咽拭子检测为阴性的患者中严重急性呼吸综合征冠状病毒2型逆转录-聚合酶链式反应检测结果的不一致性。在这个窗口内，随后阳性反应的频率为3.5%，各机构之间的情况相似。
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.
