Re: When you visit your Endo do you............
I would not take any printouts to a new doctor or to one I'm not very familiar with. Most of them resent it, viewing it as being told how to do their job. I've seen instances here where patients were actually laughed at for looking things up on the Internet. Of course, that kind of MD would be my former MD in a NY minute, but still, I wouldn't risk insulting a new MD.
Since you're paying for the tests, don't waste your money on the T4 and T3. Ask for only the free Ts. The antibody tests you want are anti-TPO and anti-Tg if you suspect you're hypothyroid; TSI and TPO if you suspect you're hyperT.
