The antibody test is just a blood test, but they send it off to a special lab (I think it's in California?) I had it at about six months or so as a precaution and it turned out negative.

My local clinic made a big deal about having to do the test because they had to ship it Fedex next day on dry ice. You'd think I was asking them to do a heart transplant as an office procedure. Sheesh! Anyway, they said if I need it again I have to have it done at the local hospital.

Sorry about the infusion mishaps, I hope next time is better.
