Health Canada Issues Public Advisory for COVID-19 Rapid Antigen Test Kits

We touched briefly in my previous blog regarding the safety issues surrounding COVID-19 rapid antigen test kits and their disposal. The solutions used in the testing kits do contain some chemicals that can pose potential health risks. Following an increase in calls to Poison Control Centres, Health Canada has issued a public advisory regarding the testing kits.

It’s important to note, that when used properly the kits are safe and a good at-home tool to help ease the spread of Covid-19. However, if accidental ingested or spilled, they may be harmful.

The two notable hazardous ingredients in most kits are Sodium azide and Proclin. These chemical preservatives can be poisonous if swallowed or absorbed through the skin, and have the potential for causing skin and eye irritation.

If you look at a Safety Data Sheet for Sodium azide, the health risks are clearly laid out. Research into the chemical classifies it as acutely toxic if swallowed, inhaled or on skin, and with risk of causing damage to several organs through single or repeated and prolonged exposures.

Thankfully, the quantities of these harmful ingredients in COVID-19 testing kits are small, however, even small quantities may cause effects in young children and pets.

Here’s what Health Canada wants you to know and what you should do:

Keep rapid antigen test kits and solutions out of the reach of children and pets.
Do not swallow the solutions, and avoid eye and skin contact.
Wash hands thoroughly after use.
If spillage occurs, rinse well with water.
Follow all instructions for proper disposal.
Report any health product-related side effects or complaints to Health Canada.
Contact your local Poison Information and Control Centre in cases of accidental ingestion of chemicals or direct skin exposure.
