Rapid antigen tests for SARS-CoV-2
Are Rapid Tests Worse at Detecting Omicron—and Does It Matter?
Anecdotal reports and results from small studies on the diagnostics’ accuracy have prompted questions about the devices’ usage with the new variant, but researchers say more data are needed and emphasize the continued importance of SARS-CoV-2 testing.
