Seek out a chiropractor/natural healer. Mine has helped me tremendously. He took the guess work out and confirmed my suspisions. I ordered my saliva and blood tests from an independent lab. My doc provided me with my ICD-9 codes (diagnosis codes). I brought the lab kit to the local hospital with the paperwork and my saliva samples. They drew blood for me and I mailed it in. My insurance company paid for the tests (shockingly).
During the course of the past year my family practice doctor ordered routine tests such as TSH with T3 and T4. This helped to reduce cost as I requested copies for my Natural health doc. Hope this helps.
