This comment looks strange to me. While I'm pretty new in the US, I find the exact procedure you're describing quite easy. All I need to do is leave an online message for my doctor asking to prescribe the test. They usually answer within hours - and I can go to the nearest lab. That, of course, given that I actually need these tests done and don't just fall on my doctor out of the sky. It sounds like you have a known condition so the doctor should have no problem figuring out why you're asking for a test.

Time to change your healthcare provider, maybe?
