|Free Triiodothyronine (Т3 free)|
Normally triiodothyronine (T3) circulates tightly bound to thyroxine-binding globulin and albumin. Only 0.3% of the total T3 is unbound (free); the free fraction is the active form of T3. Free T3 levels correlate with T3 secretion and metabolism. In hypothyroidism and hyperthyroidism level of free T3 changes in parallel with the total T3 level.
