The nasopharyngeal smear with PCR analysis is the first diagnostic test proposed to confirm infection with COVID-19 SARS-CoV-2. However, its usefulness in emergency centers is limited due to its imperfect sensitivity (56-83 %), limited availability and the time required to obtain results. For this reason, the chest CT-scan has been proposed as a rapid triage tool for diagnosis in these suspect Covid-19 patients. However, its specificity is limited, exposing to the risk of over-diagnosis, and further data are needed to confirm its usefulness, and to highlight the possible prognostic value of the CT, in detecting early lesions associated with poor outcome, indicating the need for admission to intensive care.
鼻咽涂片聚合酶链反应（PCR）分析是用于确诊新型冠状病毒肺炎（COVID-19）感染的首选诊断检测方法。然而，由于其灵敏度欠佳（56-83%）、可及性有限以及获取结果所需时间较长，其在急诊科的应用价值受限。因此，胸部CT扫描已被提议作为这些疑似COVID-19患者诊断的快速分流工具。然而，其特异性有限，存在过度诊断的风险，需要更多数据来证实其有效性，并突出CT在检测与不良预后相关的早期病变方面可能的预后价值，这表明有必要入住重症监护病房。
