FDA says CTK Biotech’s ImmuView Covid-19 Antigen Home Test that is FDA authorized under an emergency use authorization now has a longer shelf life than previously authorized. “The expiration dates for these tests have been extended to reflect the longer shelf-life,” an [agency notice](https://content.govdelivery.com/accounts/USFDA/bulletins/39c72cf?ref=fdaweb.com) says. The expiry date extension is based on additional data provided by CTK showing how long the tests can be used with the same expected accuracy, it adds.
