SAN DIEGO, CA, January 9, 2022 – ACON Laboratories, Inc. (“ACON Laboratories”), the legal manufacturer of the “Flowflex™ COVID-19 Antigen Home Test” (FDA Emergency Use Authorization EUA210494), has identified the U.S. distribution of unauthorized, adulterated and misbranded counterfeit product having the trade name “Flowflex SARS-CoV-2 Antigen Rapid Test (Self-Testing).” ACON Laboratories is not importing the “Flowflex SARS-CoV-2 Antigen Rapid Test (Self-Testing)” into the U.S. as it is only authorized for sale in Europe and other markets, under the CE mark. This press release serves as public announcement that this CE marked product is being recalled from the U.S. market. The “Flowflex SARS-CoV-2 Antigen Rapid Test (Self-Testing)” cannot be legally imported, distributed, or used in the U.S. market as it has not been approved, cleared, or authorized by the FDA. The “Flowflex COVID-19 Antigen Home Test” cannot be legally imported, distributed, or used in the European market as it is not CE marked. These two products have been authorized by the U.S. FDA and registered under CE Mark authorities separately under different product registration requirements, and therefore:
- This recall shall have no impact on the distribution and use of the CE marked “Flowflex SARS-CoV-2 Antigen Rapid Test (Self-Testing)” in Europe and other markets outside of the U.S.
- This recall shall have no impact on the distribution and use of the FDA authorized “Flowflex COVID-19 Antigen Home Test” in the United States.
Risk Statement: COVID-19 Antigen tests in the U.S. market that lack FDA approval, clearance, or authorization can pose significant risk since they may lead to inaccurate test results, including false negative or false positive test results. COVID-19 Antigen tests in Europe without the CE mark can pose significant risk since they may lead to inaccurate test results, including false negative or false positive test results.
False-negative antigen test results may lead to delayed diagnosis or inappropriate treatment of SARS-CoV-2, which may cause people harm including serious illness and death. False-negative results can also lead to further spread of the SARS-CoV-2 virus, including when people are grouped into cohorts (that is, they are housed together) in health care, long-term care, and other facilities based on these false test results. Actions to limit exposure based on false-negative results might not be taken, such as isolating people, limiting contact with family and friends, and limiting ability to work.
To date, ACON Laboratories has not received any reports of adverse events related to the products addressed in this public press release and is issuing this recall out of an abundance of caution.
