I was just bored and browsing Dynacare. They do blood tests in some provinces like Ontario and I see they have sensitive e2 test now. I know a few months ago they did not because i checked. Link below. If they do infact have it post it all over the place. Everyone in Canada has been looking for this for ages now.
