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 UC Davis Health has helped lead the way in COVID-19 testing and now is among the first in the U.S. with a rapid combined COVID/flu test. The rapid point-of-care test is a PCR-based method, which is similar to what UC Davis Health has used in its lab since March, running hundreds of tests a day, often delivering results in hours Specimen Collection & Handling of Point-of-Care and Rapid Tests. Each point-of-care test has been authorized for use with certain specimen types and should only be used with those specimen types.
