To compare sensitivity of specimens for COVID-19 diagnosis, we tested 151 nasopharyngeal/midturbinate swab pairs from 117 COVID-19 inpatients using reverse-transcriptase polymerase chain reaction (RT-PCR). Sensitivity was 94% for nasopharyngeal and 75% for midturbinate swabs (P = .0001). In 88 nasopharyngeal/midturbinate pairs with matched saliva, sensitivity was 86% for nasopharyngeal swabs and 88% for combined midturbinate swabs/saliva.
为了比较用于 COVID-19 诊断的标本的灵敏度，我们使用逆转录聚合酶链反应（RT-PCR）对 117 例 COVID-19 住院患者的 151 对鼻咽/中鼻甲拭子进行了检测。鼻咽拭子的灵敏度为 94%，中鼻甲拭子的灵敏度为 75%（P=.0001）。在 88 对具有匹配唾液的鼻咽/中鼻甲拭子对中，鼻咽拭子的灵敏度为 86%，中鼻甲拭子/唾液的联合灵敏度为 88%。
