Webb15 jan. 2024 · TBG, short for thyroxine-binding globulin, is a protein that can bind to T4 and T3. The T3 uptake test reports the percent of TBG that is bound to thyroid hormones: a higher T3 uptake % means more TBG bound to T4 or T3. This test can be helpful when abnormalities in thyroid-binding proteins make total T4 levels misleading [ 2 ]. WebbThe TBG saturation index (TBG- SI) has been used, under various names, e.g. thyroid hormone binding ratio (THBR), as a substitute for the FT4I. The TBG-SI is essentially just the ratio of total T4 to TBG, multiplied by some factor (depending on the units) so as to achieve a standard reporting scale.
