* "Maybe it was a miscommunication" is a valid question; what wasn't clear from my previous posts, because I was too pissed off to go into detail, was that that's not possible. This wasn't a tech misreading the order. The person who performed the procedure is the doctor I saw in the office, the one who tried to discount the possibility of me having celiac because I wasn't visibly in pain when he saw me (when I'd been off gluten for a month) and sometimes had constipation instead of just diarrhea (when there are people with celiac who don't have gastrointestinal symptoms at all). He was the person who did the endoscopy. And I discussed the purpose of the biopsy with the attending nurses/techs. There is no way anyone in that room thought I was there for something else.
And he was an arrogant prick to start with. But I'm willing to put up with that if the arrogant prick is also a good doctor. He's not.
So I'll call back tomorrow and stay on the line til I speak to him directly. Thank you for the links to the med board and all of the advice.
Workshop went fine, and it helped to wrench myself out of the anger and do something constructive. Now I take a nap.
