Abstract:
Rapid SARS-CoV-2 detection is essential in limiting transmission. We evaluated the performance of RT-PCR on the same nasopharyngeal swab used for Panbio antigen testing. High concordance with standard PCR and improved case detection-including asymptomatic infections-demonstrates this one-swab-two-test strategy enhances diagnostic yield while reducing patient discomfort and resource burden.
