BD, which makes diagnostic tests for a variety of conditions, announced that it has received Emergency Use Authorization (EUA) from the FDA to market its Veritor SARS-CoV-2 Antigen FIA, a rapid point-of-care test for the detection of COVID-19. The diagnostic test quickly detects fragments of proteins found on or within the virus by testing samples collected from the nasal cavity using swabs, according to the FDA

PCR (polymerase chain reaction) tests can be incredibly accurate, but running the tests and analyzing the results can take time. One of the main advantages of an antigen test is the speed of the test, which can provide results in minutes.However, antigen tests may not detect all active infections, as they do not work the same way as a PCR test. Antigen tests are very specific for the virus, but are not as sensitive as molecular PCR tests. This means that positive results from antigen tests are highly accurate, but there is a higher chance of false negatives, so negative results do not rule out infection. With this in mind, negative results from an antigen test may need to be confirmed with a PCR test prior to making treatment decisions or to prevent the possible spread of the virus due to a false negative
