Rapid antigen tests for SARS-CoV-2 yield results within minutes, but sensitivity and specificity are considerably inferior to RT-PCR tests (MMWR Morb Mortal Wkly Rep 2021; 70:100). Nevertheless, these easy-to-use tests have become popular, even though their real-world performance (especially among asymptomatic and presymptomatic individuals) has not been fully defined (NEJM JW Infect Dis Jul 2021 and Ann Intern Med 2021;174:945). Researchers in the Netherlands evaluated the performance of two commercial rapid antigen tests (Veritor [Becton Dickinson] and Biosensor [Roche]) compared with RT-PCR in the Dutch test-and-trace strategy, which stipulates that asymptomatic and presymptomatic close contacts be tested using RT-PCR 5 days after the la…
