A: Potential risks include:

• Possible discomfort during sample collection.
• Possible incorrect test result (see Warnings and Result Interpretation sections for more information).

Potential benefits include:

• The results, along with other information, can help you and your healthcare provider make informed recommendations about your care.
• The results of this test may help limit the spread of COVID-19 and flu to the family of the tested individual and others in your community.

A: There are different kinds of tests for the viruses that cause COVID-19 and the flu. Molecular tests detect genetic material from the virus, while antigen tests, such as the WELLlife™ COVID-19 / Influenza A&B Home Test, detect proteins from the virus. Due to the lower sensitivity of antigen tests, there is a higher chance this test will give you a false negative result when you have COVID-19 than a molecular test would.

A: A positive result means that it is very likely you have COVID-19 or influenza because proteins from the virus that causes COVID-19 were found in your sample. You should self-isolate from others and contact a healthcare provider for medical advice about your positive result.

A: A negative test result indicates that antigens from the virus that causes COVID-19 or influenza were not detected in your sample. However, if you have symptoms of COVID-19, and your first test is negative, you should test again in 48 hours since antigen tests are not as sensitive as molecular tests. A negative result does not rule out SARS-CoV-2 or influenza infection; you may still be infected and infect others. It is important to work with your healthcare provider to understand the next steps.

A: Clinical studies show that antigen tests more accurately determine infection when taken multiple times across several days. Repeat testing improves accuracy. This serial testing approach is recommended to minimize the risk of incorrect results.

A: An invalid result means something with the test did not work properly. A new swab should be used to collect a new nasal specimen, and you should test again with a new test.
