COVID-19 Antigen Testing

Antigen (rapid) testing is an easy and convenient way to test for COVID-19 compared to the more popular PCR testing method. The Food and Drug Administration (FDA) has granted emergency use authorization (EUA) for antigen tests that can identify SARS-CoV-2. Please use the page to learn more about antigen testing and to find out where you can acquire an antigen test for you and your family.

FAQs

COVID-19 Antigen testing is considered a faster method of detecting for COVID-19. An Antigen test is commonly used in the diagnosis of respiratory pathogens, including influenza viruses and respiratory syncytial virus. The U.S. Food and Drug Administration (FDA) has granted emergency use authorization (EUA) authorization for antigen tests that can be used to identify SARS-CoV-2 (i.e., COVID-19).

  1. Antigen COVID-19 tests have a quick turnaround time for results at 10-30 minutes and are considered screener tests. If you test positive for COVID-19 using an Antigen test then a confirmatory PCR is recommended. You may also need to retest as Antigen tests are less sensitive and may not detect an early COVID-19 infection and/or may provide a false positive.
  2. PCR COVID-19 tests are considered highly accurate and usually do not need to be repeated; however, the results need to be processed at a lab and can take 1-3 days. They are considered the gold standard of COVID-19 testing and test for the virus currently in your body.
  3. Antibody COVID-19 tests are used to see if your body may have built up antibodies for COVID-19 and does not indicate if the virus is currently active in your system.

For reference, please see: https://www.fda.gov/media/140161/download.

The performance of diagnostic tests largely depends on the circumstances in which they are used. They perform best if the person is tested when ­their viral load is generally highest. Because antigen tests perform best in symptomatic people and within a certain number of days since symptom onset, antigen tests are used frequently on people who are symptomatic. However, they can also be used to assist in screening those who have been exposed to someone who is suspected or confirmed to have COVID-19

Yes, it is recommended that you go in to your health care provider to take a Nucleic Acid Amplification Test (NAAT) to confirm results, no longer than 48 hours after the initial antigen testing. PCR (polymerase chain reaction) are classified as a type of NAAT.

NOTE ABOUT PCR TESTS: A polymerase chain reaction (PCR) test is performed to detect genetic material from a specific organism, such as a virus. The test detects the presence of a virus if you are infected at the time of the test. The test could also detect fragments of virus even after you are no longer infected.

A PCR test for COVID-19 is a test used to diagnose people who are currently infected with SARS-CoV-2, which is the coronavirus that causes COVID-19. The PCR test is the “gold standard” test for diagnosing COVID-19 because it’s the most accurate and reliable test.

Most antigen test kits will return results in approximately 10–30 minutes.

Over-the-counter Antigen Test Kits can be done at-home. You may also be able to take an antigen test at a local health clinic, pharmacy or physician’s office.  

No, you can pick up a free Antigen Test kit at any of our County or State supported testing site locations. To find a location near you, please visit: sbcovid19.com/testing-sites. You may also purchase an Antigen Test at a retail locations, through the manufacturer online or through Amazon.

Laboratory and testing professionals who conduct diagnostic or screening testing for SARS-CoV-2 with non-over-the-counter antigen tests must also comply with Clinical Laboratory Improvement Amendments (CLIA) regulations. Any laboratory or testing site that intends to report patient-specific test results to a person or healthcare provider must first obtain a CLIA certificate and meet all requirements to perform that testing. For more information, see CMS’ How to Obtain a CLIA Certificate of Waiver.

Follow the manufacturer’s instruction for use typically found in the package. Antigen tests should never be frozen and typically require to be stored at room temperature (59-86°F) before use.

Each test may be different, please refer to the manufacturer’s instruction for use typically found in the package.

Yes, fully vaccinated people who have come into close contact with someone with COVID-19 should be tested 3-5 days following the date of their exposure, but do not need to stay home. A mask should be worn in public indoor settings for 14 days following an exposure or until a negative test result. If the test result is positive, then isolate.

Please refer to the CDC for more guidelines on Quarantine and Isolation.

Although the risk that fully vaccinated people could become infected with COVID-19 is low, any fully vaccinated person who experiences symptoms consistent with COVID-19 should isolate themselves from others, be clinically evaluated for COVID-19 (i.e., active symptoms of COVID-19), and tested for SARS-CoV-2 if indicated. The symptomatic fully vaccinated person should inform their healthcare provider of their vaccination status at the time of presentation to care.
