Rapid antigen tests for SARS-CoV-2

Information on rapid antigen tests (RATs) for SARS-CoV-2 is presented. RATs detect SARS-CoV-2 antigens in samples from the upper respiratory tract and provide results in 15-30 minutes. Test sensitivities range from 30% to 80%, and specificities range from 98% to 100%, relative to reverse transcripti...

Zusammenfassung:	Information on rapid antigen tests (RATs) for SARS-CoV-2 is presented. RATs detect SARS-CoV-2 antigens in samples from the upper respiratory tract and provide results in 15-30 minutes. Test sensitivities range from 30% to 80%, and specificities range from 98% to 100%, relative to reverse transcription polymerase chain reaction (RT-PCR). RATs can detect infection in people with viral loads that are associated with SARS-CoV-2 transmission, regardless of whether they are symptomatic or not.
