високою вільної трийодтироніну (ft3) Результат випробування значення референтних для дорослих. What does high free triiodothyronine (FT3) test result referent values for adults level mean?

Upper limit of normal free triiodothyronine (FT3) test result referent values for adults is 0.5 (ng/dl) - 7.7 (pmol/L).

In normal thyroid function, as the concentrations of the carrier proteins changes, the total triiodothyronine level also changes, so that the free triiodothyronine concentration remains constant.

the increase in total triiodothyronine levels associated with pregnancy, oral contraceptives and estrogen therapy result in higher total T3 levels while the free T3 concentration remains unchanged (in normal individuals).
