What do you suggest if my tsh level is 0.11 free t4 is 15.4 free t3 (liothyronine) is 4.8 should i be on medication is so what.?

Something wrong: Hi. In the labs we use, if your FREE T4 was really 15.4, your TSH would be undetectable. Is it a total T4 (a test NO NONE should ever order, but some old docs still do)? That TSH is either a brief snapshot of a changing TSH, or if stable at that value, a hyperthyroid nodule (1 or more). We would need more history or a nuclear medicine thyroid uptakes and scan. Good luck!
