What you need to know about COVID-19 tests

If you haven’t been following the news, when you click to order your next set of free COVID-19 tests, you might find an unexpected message: “This program is not currently accepting orders for free at-home COVID-19 tests.” This doesn’t mean you can no longer get at-home tests. It simply means you’ll have to buy them.

Are at-home COVID-19 tests effective?

According to the Federal Drug Administration (FDA), an at-home COVID-19 test “detects proteins, called antigens, from the SARS-CoV-2, the virus that causes COVID-19.” When these proteins are detected, the test results are positive. If no antigens are detected, the test results are negative.

If you have a positive test, you can be fairly certain you have the virus. However, if the test results are negative, it could mean no antigens were collected during the swabbing. In other words, you might still have the virus.

Because of this, the FDA advises repeating the test in 48 hours if you have symptoms and your initial results were negative. If you were just exposed and do not have symptoms, repeat the test in 48 hours. If you have a negative result, repeat the test again in 48 hours.

How to use an at-home COVID-19 test

While collecting the sample is often the same — swabbing the inside of each nostril for a designated amount of time — every at-home COVID-19 test is performed differently. It’s important to read through all of the instructions so you understand the entire process before you tear anything open, as some may be time-sensitive and all are easily contaminated.

Will my insurance reimburse me for the purchase of an at-home COVID-19 test?

Coverage for OTC COVID-19 tests began on Jan. 15, 2022.​ However, to get reimbursed for your purchase, you must follow all instructions offered by your insurer. There may be limits on how many tests you can purchase or other stipulations that could cause your claim to be denied if you don’t follow all instructions.
