Here's how you can confirm what your new expiration may be: Look on the back of your box for both the expiration date (next to the hourglass symbol) and lot number (next to the words LOT). Visit the FDA’s website to see if your test kit’s lot number has a new expiration date. The FDA has also included a full list of all at-home COVID-19 tests that have an EUA and whether they have an extended expiration. Update 2: BinaxNOW Keeps Up with Changing Variants Virus variants. It's in their nature to change and adapt to keep themselves alive. And to have perpetually confounding nick-names, such as the most recent 'Kraken' variant. Despite the alphabet soup of variant names, it's important for our COVID-19 tests to continue to detect the virus. Our team of researchers have confirmed that our BinaxNOW tests continue to detect the Omicron variant and its sub-variants, including XBB.1.5. Why is that? While the Omicron variant contains mutations to the spike protein, our tests do not rely on the spike gene to detect the virus. Update 3: New Guidance on Testing Timing One of the benefits of at-home tests is that they can be done frequently and provide answers within minutes. As COVID-19 continues to evolve, recent research and regulatory guidance has confirmed that frequent testing – particularly when you are unsure when you were exposed – can increase the chances of catching the virus when it is detectable in people with or without symptoms.
