RE:RE:RE:RE:RE:RE:RE:Rapid TestsHealth Canada is reviewing 8 rapid antigen tests in total. Only 2 are Canadian companies, the rest are from the US, Germany, China, Korea. If you do a little research these details are easy to find. Not sure what you mean by dozens? But if you go on the Health Canada website you can see all of these details and the countries of origin for the tests. The US does not have dozens of rapid antigen test manufactures.
