The Abbott BinaxNow COVID-19 antigen self-tests now have a shelf life of 22 months. Previously, the popular test had a 15-month shelf life.
Maxim Biomedical’s ClearDetect COVID-19 antigen home test initially received authorization with an eight-month shelf life. The FDA announced that it extended the shelf life of that test to 12 months.
iHealth Labs COVID-19 antigen rapid tests received a three-month extension from 12 months to 15 months.
“The expiration dates for these tests have been extended to reflect the longer shelf-life,” the FDA said in a notice. The agency based its extension on additional data provided by the manufacturers. This data demonstrated the tests’ durability with the same expected accuracy.
