A question for anyone in the medical field?

Um... I'm hemophobic to an extreme. https://en.m.wikipedia.org/wiki/Blood_phobia

So uh a few months ago I had to get my thyroid tested. I was 17 at the time so I had to do it. (No body autonomy, you know. ) Well a very sweet nurse who I liked at a hospital did it. She drew it from my hand because I hate hate hate my inner arm being touched. If its done from my hand, I can deal.

Well my thyroid is fine but my heart is fucked up. I think I have a heart rhythm disorder. I'm going to a cardiologist soon...
First question: will they do a B test?
Second: if so, will they respect my wish to have it drawn from my hand? Yes I know it is difficult and it hurts and takes a while but I'm willing. I'm 18 now btw... I'm only going because I know I really need too...
