There isn't any bloodwork they want to draw themselves at the office anymore? This would surprise me. When I saw Dr. Chheda in January I told her I wanted to do any blood tests that could be done at any ol' Quest lab back home (washington state) for insurance reasons, but there were still labs that had to be drawn right then and there at Dr. Chheda's office such as Natural Killer Cell Function, etc because that test can only be run at the Quest lab near the office (only like 2 labs in country can do this test and 1 is there) plus the test has to be run within hours of the blood draw.
The reasoning behind this was explained to me but I forget what it was!
