Abstract
In a multicenter cohort of 22,315 patients tested for COVID-19, 1676 (7.5%) had repeat testing via real-time polymerase chain reaction following an initial negative test. Of those retested within 7 days of their first negative test, only 2.0% had a positive result. This suggests that repeat testing from the same source is unlikely to provide additional information.
摘要
在一项针对 22315 名接受 COVID-19 检测的患者的多中心队列研究中，1676 名（7.5%）患者在首次阴性检测后通过实时聚合酶链反应进行了重复检测。在首次阴性检测后 7 天内进行复测的患者中，只有 2.0%的患者检测结果为阳性。这表明，来自同一来源的重复检测不太可能提供额外的信息。
