FAQs

An Over-the-Counter COVID-19 Antigen test is a none-prescribed rapid self-administered test that may be found at your local County testing sites or available for purchase online or in store. These test may be performed at home, in your car and other locations to detect COVID-19 infection and receive results within 10 – 15 minutes.

Please visit the CDC website to learn more about these COVID-19 at-home tests.

The U.S. Food and Drug Administration (FDA) has authorized at-home over-the-counter (OTC) COVID-19 tests under the Emergency Use Authorization (EUA).  

To see a list of FDA approved OTC COVID-19 tests, visit the FDA website here.

At-home over-the-counter tests are typically 80% accurate in detecting an infected individual compared to PCR COVID-19 tests that have a 95% accuracy.

When using at-home over-the-counter tests, the FDA recommends that a person repeats testing when receiving a negative test result; this is especially true for asymptomatic individuals. Findings have found that symptomatic individuals testing two times separated by 48 hours, increase the detection and accuracy of the SARS-COV-2 infection result by more than 90%. In asymptomatic individuals, repeated testing of 3 times every 48 hours, increases the test result accuracy by 79%.

To optimize results using a COVID-19 Antigen test, please ensure you follow the Instructions for Use found in your antigen test package and repeat testing as recommended.

For more information visit the FDA website.

COVID-19 Antigen test should never be frozen and typically require to be stored at room temperature (59-86 F). Please follow the manufactures instructions for use (IFUs) found in the package.
