Across the country including here in East Texas, people are scrambling to either get tested for COVID or get their hands on "at-home" or "rapid" tests. The FDA has issued a warning about 2 of these tests that could give you wrong results. If you spot them, don't use them.

These tests have NOT been authorized, cleared, or approved by the FDA for distribution or use in the United States.

The FDA believes that these tests were distributed for use in laboratories or for at-home testing.

The LuSys Laboratories COVID-19 Antigen Test (Nasal/Saliva) uses a nasal swab or a saliva (spit) sample intended to detect proteins, called antigens, from the SARS-CoV-2 virus. The LuSys Laboratories COVID-19 IgG/IgM Antibody Test uses serum, plasma, or blood samples.
