Clinical Information:
Triiodothyronine (T3) is a thyroid hormone with a molecular weight of 651 daltons  and a half-life in serum of 1.5 days. T3 circulates in the blood as an equilibrium mixture of free and protein bound hormone. T3 is bound to thyroxine binding globulin (TBG), prealbumin, and albumin. The actual distribution of T3 among these binding proteins is controversial as estimates range from 38-80% for TBG, 9-27% for prealbumin, and 11-35% for albumin. The binding of these proteins is such that only 0.2-0.4% of the total T3 is present in solution as unbound or free T3.This free fraction represents the physiologically active thyroid hormone. Total T3 assay is to be used as an aid in the assessment of thyroid status.
