Well, your partner had genital herpes but 15 years ago, most of that was HSV 2, not HSV 1 though it could have been HSV 1. If it was HSV 1, the transmission rate of HSV 1 through intercourse is low but now zero. I agree there is much room for confusion. I am horrified that it cost you $300 for an IgG antibody test that would cost perhaps $50 in the US. You can ask the UW to send you a test kit, have you blood drawn and send it back to them. I think it is about $200. I doubt you can get it done in Canada. I would google herpes western blot Canada and see what you get. Lots of people in Canada manage to get it, but aside from getting the test kit and returning it, I’m not sure how they do it.
