Some at-home rapid COVID-19 tests contain a toxic chemical that may be harmful to both children and adults, according to health officials.
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.
“Mostly, I’ve been very worried about our young children.”
“People might mistake them for eye drops. Children might drop it onto their skin. Adults will sometimes mistakenly put them into their eyes,” she said.
“You don’t want to leave it on the skin because it could potentially cause an allergic reaction or a skin rash.
“If someone drinks the solution, it’s really important to contact poison control right away. The solutions have different ingredients. Some have non-toxic ingredients and others have more dangerous ingredients.”
Officials told WNEP that there’s no need to throw away the test kits, but people should be mindful when using them.
“Use them properly, dispose of them properly, and it won’t cause an issue,” Dr. Jeffrey Jahre, with St. Luke’s University Health Network, told the outlet.
