How accurate are rapid antigen tests?

As of May 2022, the U.S. is experiencing another uptick in the number of COVID-19 cases.

High rates of infection in Europe and Asia, along with the continued emergence of new sub-variants, such as omicron BA.4 and BA.5, raise concerns that another surge could be on the way.

Even though demand for COVID-19 tests greatly overwhelmed supply earlier in the pandemic, rapid home tests are more available today.

While home tests provide a quick, accurate result, the flip side is that many test results are no longer reported to health authorities.
