What is the problem and what is known about it so far? SARS-CoV-2 tests are an important tool to help manage the COVID-19 pandemic. Reverse transcriptase polymerase chain reaction (RT-PCR) tests are typically done in testing centers, often require scheduling, and can take days for results to be available. Rapid antigen tests that people can do at home make testing easier and enable immediate changes in behavior if the result is positive. Although rapid antigen tests are known to perform well in diagnosing infection with the Delta variant and other earlier SARS-CoV-2 variants, it is not clear howwell they perform in diagnosing infection with theOmicron variant.
