This obviously will result in low levels of
Free T3 and
Free T4. To find out, you need to test
for Free T3 and
Free T4, along with TSH each time you go in for followup. If the doctor resists, then you should insist on it for the above reasons, and don't take no for an answer. Since hypothyroid patients are frequently low in other areas as well, I suggest that you should also test for Vitamin A, D, B12 and ferritin.
