Be sure they run Free T3 and Free T4, not Total T3 and T4. If they resist, just insist and don't take no for an answer. I would even go so far as to get the lab people to confirm it is going to be for Free T3 and Free T4. Otherwise they often revert to the usual, which doesn't include the Frees.
Also, since hypo patients are frequently too low in the ranges for Vitamin D, B12 and ferritin, I also suggest testing those as well.
Thanks so much for your input. I have appt. tomorrow and will post labs as soon as I get them.

Those symptoms are not due to the Synthroid, but instead due to an inadequate dosage, or if the dosage is adequate, then your body is not adequately converting the T4 to T3. Free T3 largely regulates metabolism and many other body functions. Scientific studies have shown that Free t3 correlated best with hypo symptoms, while Free T4 and TSH did not correlate at all.
So, please post your thyroid related tests and reference ranges shown on the lab report, so that members can assess the adequacy of your testing and treatment. Also, what is your daily dosage of Synthroid?
