The question whether this new variant has an impact on SARS-CoV-2 rapid antigen test (RAT) performance is of utmost importance. Rapid tests that give near instant results, without the need of a laboratory, offer much promise. These findings indicated that the antigen check was delicate sufficient to detect BA.1 and BA.2 variants, the 2 main sub-lineages of SARS-CoV-2 Omicron. A small preliminary study that was recently published concludes that “most omicron cases were infectious for several days before being detectable by a rapid antigen test.” It pays to be cautious.
