2021-3-16 · Compared to PCR tests, antigen tests are more likely to miss an active COVID-19 infection early in its course or due to low viral load. If infected and asymptomatic for COVID-19, a PCR test is likely to detect the virus. A PCR test can detect infection at lower levels than a rapid antigen test.
