Good question. Here in the United States it is not required by any clinic as a state or federal law. However if the clinic (HT) has a standard practice of blood work prior to a surgery, then it is usually drawn from your private/family/general physician's office. Or you can ask the HT clinic to order the blood work for you and you go to your local laboratory.
We do check HIV, Hep, coagulation, as a precautionary for all concerned, but nothing to do with acceptance for a procedure. Also Dr. B finds it can help sometimes with the dosage level of meds he gives and on a few occasions it has shown some patient's levels to be slightly low that they were not aware of so they could visit their GP and have a proper check.
I do have to say my bloodwork at BHR went very smooth and Natascha did a wonderful job. It might not matter for some, but for some reason my eyes always roll into the back of my head and I pass out. I am not sure why because I don't have a problem with pain. It has even had happened while I have been in the reclined position.
Even my longtime girlfriend was worried because on my last blood test we were together. She had to slap me in the face a few times to bring me back and I think it really shook her up a bit. But Natascha really did a wonderful job and was very gentle, which made all the difference.
I don't say any of this too lightly. It was really one of my biggest concerns and I mentioned to BHR a few times before ever having my procedure.
