COVID-19 Rapid Testing

COVID-19 rapid results diagnostic tests can show if you are currently infected with SARS-CoV-2, the virus that causes COVID-19. This is an antigen test, often referred to as a rapid test.

Rapid (Antigen) Test vs. PCR Test

In short, antigen tests produce faster results and are easier to perform than PCR tests, which must be administered by a healthcare professional. However, antigen test results are less reliable than PCR results as they are more likely to produce false negatives.

 

Antigen tests detect specific viral proteins that are present in the body during infection. These proteins indicate the presence of the virus, but they are not the virus itself. These tests are only able to detect these proteins when the virus is most active and infectious, during the “peak” of infection. Rapid tests are likely to produce false negatives during the incubation period and post-infectious phases.

 

PCR tests, on the other hand, detect the genetic material of the virus itself through an RNA sample. This eliminates potential interference from other viruses, making the test more reliable. However, results may take several days as opposed to 15 minutes for rapid tests.

COVID Testing for Travel

Many places around the world still require negative COVID tests for incoming and returning travelers.

 

Infection cannot be ruled out by a single negative antigen test result. A rapid test does not have the same reliability as PCR tests, especially in people without symptoms. It is recommended that a negative antigen test be repeated at least 48 hours apart to more confidently rule out infection. To confirm the antigen test result, a follow-up NAAT may be recommended.
