Your body makes antibodies after it’s infected by a virus or other infectious agents, or after you receive a vaccination. That is what the Government of Canada has been stating on its website. The screenshot is from the Government of Canada website. I’ll repeat what it states: “If you have a positive serology test result, it’s likely that you previously had a COVID-19 infection and that you developed an antibody response to the virus. It may also indicate that you developed antibodies in response to vaccination.”
“Serological testing detects the presence of antibodies, not the presence of the SARS-CoV-2 virus. This testing is also not to be used to diagnose infection.”
The overwhelming majority of COVID-19 test kits used to diagnose new COVID-19 cases in Canada, the US and UK are serological test kits which “do not detect the virus itself“. That being said, Canada’s federal and provincial governments claiming that there are x number of new cases of COVID-19 is completely and utterly false.
If serological test kits do not detect the virus that causes COVID-19 then logically and factually Canadians are not being tested for COVID-19 and they haven’t tested positive for COVID-19.
Stated by Johns Hopkins Medicine, the FDA, Health Canada, and product inserts for Assure, TBG, ACON, MEGNA & BIOTIME COVID-19 IgM/IgG Antibody Rapid Test Kits:
“Results from antibody testing should not be used to diagnose or exclude SARS-CoV-2 infection or to inform (COVID-19) infection status.”
COVID-19 IgM/IgG Antibody Rapid Test Kit insert:
“False positive results for IgM and IgG antibodies may occur due to cross reactivity from pre-existing antibodies or other possible causes.”
“Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E”
