Any doctor can order any kind of blood work, but the limitation as you've found is the ability to properly interpret it.
40M 5'8 160 pounds. As part of my team of doctors (3 cardiologists, primary care doc, endocrinologist, neurologist, etc.), we've been hunting down some autonomic issues that I have been having. I haven't had blood work in a couple of years because I have been pending Disability since last year and had a work injury the year before that. My autonomic issues worsened over that time.If TLDR, can a Cardiology office request the same type/amount of blood work as a primary care doc, for instance?I don't have a primary care doctor presently because I had a good one and he moved away back to his home state a while ago. Most primary care doctors are unfamiliar with specific autonomic dysfunction conditions, so my third cardiologist is the specialist in autonomic issues. They want to do blood work. Of course, I'm asking their office what kind of blood work they can do, as well. But since it may be days before they can get around to that general question, this is a two-part question:I'm wondering if any doc can explain the difference between which offices (primary care, cardiology, endocrinology, etc.) can do what types of blood work and if they are 'limited' in what types they can request.Also, is that that limitation solely based on the provider themselves being medically unable to request beyond specific blood work related to their specialty or is it just because they're not familiar with other blood values? For instance, I asked my neurologist one time about blood work values from a cardiology tilt table test and he said he "didn't know how to read those blood gas levels". So that told me that of course that's not his specialty, and I knew that, but he was the one who asked about blood work to begin with.
