I work with people in Canada to get the blot all the time. The people at UW can work out shipping you a kit if you get them a shipping label. Then you could have a teleconference with me. I don’t believe the blot is available anywhere in Canada.
Even if the cut is small, it can be swab tested and it should be swabbed on the first day that it appears, ASAP.
I’m not clear that repeating the IgG would be useful for you.
