Thyroid (increased T3 (liothyronine) and t4). What does this mean? Should I be concerned?

In brief: Tell us TSH

Hi. Not enough information.
Is TSH below normal? That's VERY important to know. T4 and T3 (liothyronine) can be elevated due to elevated thyroxine binding globulin (TBG) with completely normal thyroid function. It's better to measure free T4 and free T3 (liothyronine) than T4 and T3 (liothyronine) per se. So I can't tell you if anything is even abnormal without more information.
