It's pretty obvious that your doctor is placing too much reliance on your TSH and not even looking at how low the FT4 is, in its range. Testing TT3 instead of FT3 is a dead give away that she's not thyroid savvy.
I'd recommend that you try to find a different doctor, unless you think you can get this one to test FT3 and FT4, as well as TSH and pay more attention to your symptoms. Some doctors are willing to be "educated"; others are so arrogant that they get upset when they find out their patients have been researching and will no longer follow them blindly.
Thank you very much fro you information. I definitely feel lost in this realm and kick myself for listening to her advice for the last 10 years stating being in the range is ok and only testing TSH till this month.
It is a relief to now have an idea where to start. Thank you very much!
Your TSH is too high, even though the range goes up to 4.82. Over 10 yrs ago, AACE recommended that the reference range for TSH be lowered to 0.3-3.0. Labs (therefore doctors) have been slow (to put it mildly) to react.
Additionally, your doctor is testing total T3, rather than Free T3, which is the actual hormone used by individual cells. Even at that, your Total T3 isn't even in range. Along with that, your FT4 is so low in the range, I can see why you have symptoms. I'm finding it hard to trust your doctor when s/he says nothing needs to be done at this time. Apparently, s/he isn't a good thyroid doctor.
Looks like you could benefit from an increase in dosage and maybe even the addition of a T3 med, but without a Free T3 test, we can't know that. With your FT4 as low as it is, there just may not be enough to convert well.
