We enrolled 91 consecutive inpatients with COVID-19 at 6 hospitals in Toronto, Canada, and tested 1 nasopharyngeal swab/saliva sample pair from each patient using real-time RT-PCR for severe acute respiratory syndrome coronavirus 2. Sensitivity was 89% for nasopharyngeal swabs and 72% for saliva (P = .02). Difference in sensitivity was greatest for sample pairs collected later in illness.
我们在加拿大多伦多的 6 家医院招募了 91 名连续住院的 COVID-19 患者，并使用实时 RT-PCR 对每位患者的 1 对鼻咽拭子/唾液样本进行检测，以检测严重急性呼吸综合征冠状病毒 2。鼻咽拭子的敏感性为 89%，唾液为 72%（P =.02）。在疾病后期采集的样本对之间的敏感性差异最大。
