Referrals normally have to do with an HMO plan. With an HMO, you have a primary care physician. If you need to go to a specialist, like a cardiologist for heart conditions or a dermatologist for skin conditions, the HMO insurance company wants your primary care physician to "Refer" you to that specialist. It's basically an adminstrative way of keeping track of the doctors visits that you go to. If you have a PPO, you don't need referrals to go to a specialist.

Perhaps you need to switch to Armour Thyroid which is real thyroid and helps with low T3 and T4. The lab tests are faulty. They don't always us the best tests at the labs and many don't test the T4 level. Ask your doctor to switch you to Armour Thyroid. The cost is about the same and you won't be taking a synthetic form of thyroid. The synthetic form does not work well. He could start you out on 2 grains of the armour thyroid. If he does not like the idea then go to a hormone specialist and get better treatment.
