When to test and understanding the results
A rapid COVID-19 test can help protect you and your family if used properly. Please consult the HHS How to do a COVID-19 Rapid Antigen Self-Test document for instructions on how to perform the test. A rapid test should be taken just before getting together with friends or family. However, the test is most reliable in the moment it is administered. This means that even though you may have a negative test, you could test positive later in the day. If your test is positive, you should isolate and confirm with a PCR test as soon as possible.
A COVID-19 rapid test is not recommended if you have symptoms. Healthcare workers who have symptoms or have been in close contact with a known COVID-19 case should contact HHS Employee Health Services for instructions even if they have a negative result using the rapid test. Rapid tests are not a replacement for PCR tests (swabbing). Even with a negative rapid test, an individual may be infected. Everyone should continue to follow public health measures: limit gathering size, wear PPE as appropriate, wash your hands, and get
vaccinated. Please consult Ontario Health’s handout for more information and best practices on rapid antigen tests
