Re: getting closer to finding the cause of my disorder
As a Chiropractic Physician who worked alongside Medical Physicians for eleven years, I've seen that doctors do not like to order unnecessary tests. "Unecessary" meaning if these test results were abnormal, what would the medical treatment be? Moreover, insurance companies won't cover the costs of unnecessary or experimental tests. That said, if you have a good relationship with your PCP. and you are willing to pay for the tests, he/she may order them for you.
However, the results you're looking for appear to be more in the realm of research studies vs. clinical medicine. As such, you might have better luck contacting those working in clinical trials in your areas of interest (http://www.clinicaltrials.gov
trials, as listed by LBDA) and seeing if they could connect you to a MD clinician/researcher who might be interested in ordering these tests. Good luck!
