Public Alert No. 048/2022 – Warning Against Counterfeit Covid-19 Antigen Rapid Test Kits

December 14, 2022,

The National Agency for Food and Drug Administration and Control (NAFDAC) is notifying healthcare providers of a safety communication by Health Canada following the discovery of counterfeit BTNX Incorporated COVID-19 rapid antigen test kits in Ontario, Canada. The counterfeit test kits were sold online in 25-pack boxes by a distributor called Healthful Plus without the required licence.

The packaging of the counterfeit kits resembles the authentic (licensed) BTNX Inc. products in colour and typeface and uses the BTNX Inc. device identifier “COV-19C25”, but also has several key differences. The counterfeit kits:

  • are labelled as manufactured by “Health Advance Inc.” instead of BTNX Inc.;
  • lists Health Advance as an “Official Canadian Distributor”; and
  • includes the text “Health Canada Approved”. Claims of endorsement by government authorities, such as Health Canada, are not permitted.

Genuine COVID-19 Antigen test helps detect certain proteins in the virus. Rapid antigen tests are designed to tell in a few minutes whether someone is infectious or not. It is recommended as a high performing test for individuals with symptoms, high-risk populations, and healthcare or casual workers.

Counterfeit health products are imitations of authentic products. The safety and effectiveness of these counterfeit test kits have not been assessed.

The genuine manufacturer BTNX Inc. has confirmed that the devices were counterfeit. 

The table below shows the difference between the counterfeit and authentic COVID-19 rapid antigen test kit;
