Since the launch of its Flowflex COVID-19 Antigen Home Test, ACON Laboratories, Inc. has continued testing for product stability to extend the shelf-life. These results have been shared with the FDA. We are pleased to announce that the request to extend the Flowflex COVID-19 Antigen Home Test shelf-life from 12 months to 21 months, when stored at 36-86°F (2-30°C), has been granted.

The Flowflex COVID-19 Antigen Home Test has an expiration date that is extended by 9 months. Refer to the table for the new expiration date using the lot number printed on the test kit box.

Future shelf-life expiration date extensions will be communicated as they become available.
