Rapid antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are effective tools for the diagnosis of acute infection, particularly when used serially.¹ The percentage of rapid antigen tests with false positive results is reported to be less than 1%.² However, we have observed persons who repeatedly test positive with rapid antigen tests despite concurrent negative molecular tests; this infrequent phenomenon occurs predominantly among women and persons with autoimmune disorders.

Covid-19 快速抗原检测持续假阳性

严重急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 的快速抗原检测是诊断急性感染的有效工具，特别是连续使用时。¹据报道，快速抗原检测出现假阳性结果的百分比低于 1%。²然而，我们观察到，尽管分子检测结果呈阴性，但快速抗原检测结果却反复呈阳性；这种罕见现象主要发生在妇女和患有自身免疫性疾病的人中。
