FDA Warns Consumers Not to Use LuSys Laboratories COVID Tests Due to False Results
On January 12, 2022, the FDA issued a warning to consumers informing them to stop using LuSys Laboratories COVID-19 Antigen Test (Nasal/Saliva) and LuSys Laboratories COVID-19 IgG/IgM Antibody Test due to a "high risk of false results" when using these tests. Neither test has been authorized, cleared, or approved by the FDA. To date, no saliva-based antigen test has been authorized or approved by the agency.
LuSys Laboratories COVID-19 Antigen Tests (Nasal/Saliva) and COVID-19 IgG/IgM Antibody Tests may also be sold under company names Luscient Diagnostics or Vivera Pharmaceuticals, or with the trade name EagleDx. The tests may have been distributed for use in laboratories or for at-home testing.
According to the agency, both tests may produce false positive or false negative results, which could result in a delayed and proper diagnosis and appropriate treatment.
People who have used these tests and have concerns regarding the results should contact their health care provider.
