I'm a 38M smoker.

So this company called Epicgenetics sent me a test for fibromyalgia (I've had Epstein-Barr, and my mom was diagnosed with it. I have severe chronic pain.) The PA I see won't sign off on the paper work for me to take it because she said she's never heard of the company before, even though when you Google it you can find several reputable articles about it. I would talk to the doctor about it, but apparently the people who work there don't like it when you ask for the doctor. I've never actually met the guy. Anyway, should I find a new practitioner or go with her advice? It sucks because Medicare was going to pay for the test, and I really want to know.
