Tsh 0.01, t3 (liothyronine) 4.3 t4 1.8 ? my thyroid test always normal for,years ? what is going on? help please..

It depends,,: It depends on the units of measurement used in these results, at least for the t3 (liothyronine). If it was ng/dL, then it's really low, if nmol/L, then it's somewhat high, but the other values are definitely low so there may be something going on. Whatever it might be, a visit to your doctor for discussion and a possible repeat of the tests is likely the best thing to do at this time. Best of luck.
