“Some at-home rapid COVID-19 tests contain a toxic chemical that may be harmful to both children and adults, according to health officials.
The Cincinnati Drug and Poison Information Center reported an uptick in accidental exposures to a possibly toxic substance in at-home COVID-19 test kits, accordingto a blog post. Meanwhile, the National Poison Control Center issued a warning about the chemical.
“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 said. “The BinaxNow, BD Veritor, Flowflex, and Celltrion DiaTrust COVID-19 rapid antigen kits all contain this chemical.”
Sodium azide is a colorless, odorless powder that testers dip cotton swabs into. The chemical is found in herbicides, pest control agents, and airbags for cars.
“Small doses of sodium azide can lower blood pressure, and larger doses may cause more serious health effects,” an advisory from Health Canada also said. “ProClin is also found in many kits. It contains chemicals that can cause skin and eye irritation, as well as allergic reactions.”
Some hospitals around the United States say they have received a surge in phone calls about exposures to the chemical.”
