I saw this a while back on the FDA – Counterfeit At-Home OTC COVID-19 Diagnostic Tests: https://www.fda.gov/medical-devices/coronavirus-covid-19-and-medical-devices/counterfeit-home-otc-covid-19-diagnostic-tests/. Longer article.
The FDA is aware of counterfeit at-home over-the-counter (OTC) COVID-19 diagnostic tests being distributed or used in the United States. These counterfeit tests should not be used or distributed.
Counterfeit COVID-19 tests are tests that are not authorized, cleared, or approved by the FDA for distribution or use in the United States, but are made to look like authorized tests so the users will think they are the real, FDA-authorized test. The performance of these counterfeit tests has not been adequately established and the FDA is concerned about the risk of false results when people use these unauthorized tests.
You may risk unknowingly spreading COVID-19 and may delay or stop appropriate medical treatment for COVID-19 if you use a counterfeit test.
