A private clinic is reportedly set to roll out COVID-19 antibody testing.

A Toronto Star report quotes a spokesperson for executive healthcare clinic Medcan as saying the test will be offered starting next month, at a price.

It’s one of five serological tests approved by Health Canada.

Unlike a swab test which determines if someone has an active infection, this is a blood test which shows whether a person has developed antibodies that suggest they’ve already had COVID-19 and could be protected from getting it again.

The antibody test is already being widely used in many countries, including the U.S.

Experts have urged caution. There are concerns with accuracy and false positives. Scientists have also not proven with strong evidence if you have the COVID-19 antibodies that you are immune from getting the virus again.
