Does rhinoplasty require a pre-op assessment?

Hi, I have booked rhinoplasty with a great surgeon and have had two consultations with that surgeon. However, I have been informed that I do not have to see the surgeon again until the day of surgery. I have heard of people having pre-op appointments with their surgeons where blood samples and possible urine samples are taken but I was wondering if not having these tests was normal with plastic surgery or whether I should be having them? Many Thanks.
