Utilizing results of polymerase chain reaction (PCR) testing and subsequent antibody titers, we report on the test characteristics of a PCR screening test for severe acute respiratory syndrome coronavirus 2 among hospital workers. The PCR test was found to be 87% sensitive and 97% specific, with a positive predictive value of 0.98 and a negative predictive value of 0.80.
利用聚合酶链反应（PCR）检测结果及后续抗体滴度，我们报告了医院工作人员中针对严重急性呼吸综合征冠状病毒2的PCR筛查检测的检测特征。发现该PCR检测的敏感性为87%，特异性为97%，阳性预测值为0.98，阴性预测值为0.80。
