We performed a prospective study of 501 patients, regardless of symptoms, admitted to the hospital, to estimate the predictive value of a negative nasopharyngeal swab for severe acute respiratory coronavirus virus 2 (SARS-CoV-2). At a positivity rate of 10.2%, the estimated negative predictive value (NPV) was 97.2% and the NPV rose as prevalence decreased during the study.

우리는 중증 급성 호흡기 코로나바이러스 2(SARS-CoV-2)에 대한 음성 비인두 면봉 검사의 예측값을 추정하기 위해 증상과 상관없이 병원에 입원한 501명의 환자를 대상으로 전향적 연구를 수행했습니다. 10.2%의 양성률에서 추정된 음성 예측 값(NPV)은 97.2%였으며 연구 기간 동안 유병률이 감소함에 따라 NPV는 증가했습니다.
