If you test positive: Take another test to verify the result. If it’s still negative when you retest, then it’s possible any symptoms you have aren’t Covid-related. As per the CDC, it’s possible the sample was collected too early in the infection and may show up positive after a few days. The same goes if you test negative and aren’t experiencing any symptoms-especially if you’ve been to a gathering with several people. If you test negative: Experiencing Covid-19 symptoms but got a negative test result? Take another test, following the manufacturer’s instructions (usually within two to three days). If you were in close contact with someone who contracted the virus, you should test yourself at least five days after exposure and wear a mask around other people for 10 days. According to the US Centers for Disease Control and Prevention, those who are experiencing Covid symptoms should test immediately. When Should I Take an At-Home Covid Test? To test for both, you'll have to purchase the $99 single-use test kit.
Lucira is also the first at-home test to receive FDA authorization for both Covid-19 and flu. Reuse those batteries for another device. We're recommending it now solely based on its more affordable price of $29-down from $68.
It's powered by AA batteries and is single-use, which means you have to throw the entire thing out after you're done testing. There's also a label for an invalid result, which means you should repeat the test.Įven though Lucira is the most accurate on this list (the company claims 98 percent accuracy), we've kept it off in the past mainly because it's wasteful. After 30 minutes, you'll see a green light next to the positive or negative label, depending on the result. It's easy to use-place the vial of solution into the reader, swab both nostrils, stir the swab in the solution, snap the vial closed, and push it further down into the reader.

Lucira doesn't require a smartphone, but you can download the Lucira Connect app to keep a test record. As for the hack, Ellume says it has fixed the issue. Ellume tests currently available for purchase are safe to use and are not impacted by the recall-the connected app won’t let you proceed with the test if it’s the version that was recalled. But an Ellume spokesperson says all affected tests have been pulled from store shelves and online retailers since then. In December, security researchers found that they were able to fabricate positive or negative test results through Ellume’s Bluetooth-enabled test device. We previously listed Ellume as an “At-Home Covid Test to Avoid” because it was recalled due to “higher-than-acceptable false-positive test results” for Covid-19 back in October and November of 2021. I received my results via the app with no issue. Ellume’s analyzer has a mechanism that detects if a sufficient amount was collected to help reduce the chance of false negatives. I wasn’t able to stick the swab as far up my nasal passages as I had to (I only made it about halfway), but that’s probably not the case for everyone. The higher the concentration, the more accurate the diagnosis. Then there’s the swab-rather than the standard nasal swab found in most tests, Ellume uses a patented flock tip that requires going deeper into your nostrils to collect a higher viral concentration.

The cassette comes equipped with Bluetooth and connects to your phone via a companion app. Įllume’s test sets itself apart from others on this list for multiple reasons. You can find the exact signs to look for here. The FDA also issued a warning for another set of fraudulent versions being distributed in April 2022. (It came in a dark blue box.) Make sure to look for tests called FlowFlex Covid-19 Antigen Rapid Test in a white box. In January 2022, the FDA recalled a counterfeit version called Flowflex SARS-CoV-2 Antigen Rapid Test (Self-Testing) that hasn’t been authorized for sale in the US. Warning: If you’re shopping for the FlowFlex, make sure it comes in a white box. This test comes in a much more compact box and is easier to unbox and use than some tests we tried. After 15 to 30 minutes, your results will appear. The process is similar: Swab your nose, dip the swab in the solution, and squeeze a few drops onto a small plastic test card. But unlike the others, the FDA is confident enough in this one that it doesn’t advise you to test yourself again after a few days-unless you feel new symptoms coming on. Unlike nearly every other test kit, you only get one test per box with FlowFlex.
