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.
