Rapid COVID-19 Testing

Rapid COVID-19 Test

Rapid COVID-19 test is a fast, easy, reliable test for detection of SARS‑CoV‑2 (the novel or new coronavirus that causes COVID-19) antigen. After using a nasal swab, test results can be obtained in as little as 15 minutes. 

Rapid SARS-CoV-2 antigen test provides information to actively detect the virus and decrease the likelihood of spread, facilitate return to work, and be able to travel. 

We use the FDA approved Becton Dickinson BD Veritor™ Plus System. Your airline may require a proof of negative COVID-19 test prior to travel. Check with your airline and destination to determine if Becton Dickinson (BD Veritor™) antigen test is approved for clearance for your flight and destination.

What does it mean if I have a positive test result?

If you have a positive test result, it is very likely that you have COVID-19. Therefore, it is also likely that you may be placed in isolation to avoid spreading the virus to others. There is a very small chance that this test can give a positive result that is wrong (a false positive result). Your healthcare provider will work with you to determine how best to care for you based on your test result(s) along with your medical history, and your symptoms. 

What does it mean if I have a negative test result?

A negative test result means that proteins from the virus that causes COVID-19 were not found in your sample.  It is possible for this test to give a negative result that is incorrect (false negative) in some people with COVID19. This means that you could possibly still have COVID19 even though the test is negative. If your test result is negative, your healthcare provider will consider the test result together with all other aspects of your medical history (such as symptoms, possible exposures, and geographical location of places you have recently traveled) in deciding how to care for you. The amount of antigen in a sample may decrease the longer you have symptoms of infection. Specimens collected after you have had symptoms for more than 5 days may be more likely to be negative compared to a molecular assay.

What are the differences between antigen tests and other COVID-19 tests?

There are different kinds of diagnostic tests for COVID19. Molecular tests (PCR) test detect genetic material from the virus.  Antigen tests detect proteins from the virus. Antigen tests are very specific for the virus, but are not as sensitive as molecular tests. This means that a positive result is highly accurate, but a negative result does not rule out infection.
