Poison control issues warning regarding take-home antigen COVID-19 tests

The National Capital Poison Center issued a warning about the liquid found in many antigen COVID-19 tests, reminding users that it is dangerous to ingest.

“It is important to know that the extraction vial in many rapid antigen kits includes the chemical sodium azide as a preservative agent,” the center reported. “The BinaxNow, BD Veritor, Flowflex, and Celltrion DiaTrust COVID-19 rapid antigen kits all contain this chemical.”
