We report a case of false-positive results for SARS-CoV-2-specific antigen. A patient initially had positive results on immunochromatographic SARS-CoV-2-specific antigen test, followed by negative results on RT-PCR assay of saliva and SARS-CoV-2-specific antibody test. Nasopharyngeal swab reexamination using immunochromatographic tests showed weakly positive results, warranting confirmation with high-specificity tests.

需要高特异性试验以确认免疫层析SARS-CoV-2特异性抗原试验中的弱阳性结果：病例报告
我们报告一例SARS-CoV-2特异性抗原假阳性结果。最初，患者的免疫色谱SARS-CoV-2特异性抗原检测结果为阳性，随后唾液的RT-PCR检测和SARS-CoV-2特异性抗体检测结果为阴性。鼻咽拭子的免疫层析检测复检结果较弱，需要通过高特异性检测进行确认。
