Among hospitalized persons under investigation for coronavirus disease 2019 (COVID-19), more repeated severe acute respiratory syndrome coronavirus 2 nucleic acid amplification tests (NAATs) after a negative NAAT were positive from lower than from upper respiratory tract specimens (1.9% vs 1.0%, = .033). Lower respiratory testing should be prioritized among patients displaying respiratory symptoms with moderate-to-high suspicion for COVID-19 after 1 negative upper respiratory NAAT.
在因2019冠状病毒病(COVID-19)接受调查的住院患者中,核酸扩增检测(NAAT)结果为阴性后,下呼吸道标本的严重急性呼吸综合征冠状病毒2重复NAAT检测呈阳性的比例高于上呼吸道标本(1.9%对1.0%,P = 0.033)。对于上呼吸道NAAT检测结果为阴性但高度怀疑COVID-19且有呼吸道症状的患者,应优先进行下呼吸道检测。
