I would like to point out that my endocrinologist admitted that my full set of thyroid measurements were 'unusual' (some of the measurements, maybe free T4 and T3, were a bit high/low in one test, and reversed in the second one, which he obviously felt was odd enough to be worth mentioning), but then he just brushed that off and said it was Hashimoto's Thyroiditis, take synthroid, end of discussion. That's when I pointed out the other stuff and he got angry. How dare I challenge his amazing diagnosis that must have taken him several seconds to reach? Nope, not impressed with endocrinologists.
A few differences but that was pretty much my interaction with quite a few endo's/internalists
