The case refers to a 51-year-old symptomatic man with a new SARS-CoV-2 RNA positive nasopharyngeal swab after two negative ones and the lack of significant development of antibody response measured by different diagnostic serological test. Our case underlines that a discrepancy between clinical course of SARS-CoV-2 infection and results from diagnostic tests may exist. This concept is rapidly emerging and supports the need for a deep knowledge of available and “in development” tests for a correct interpretation of their findings.

SARS-CoV-2 感染：诊断检测结果偶尔需要特别注意。

该病例是指一名 51 岁有症状的男性，在两次鼻咽拭子阴性后，新的 SARS-CoV-2 RNA 呈阳性，并且通过不同的诊断血清学检测未出现明显的抗体反应。我们的案例强调，SARS-CoV-2 感染的临床过程与诊断测试结果之间可能存在差异。这个概念正在迅速出现，并支持对可用和“开发中”测试的深入了解以正确解释他们的发现。
