Thyroid hormone uptake (T uptake or T 3 uptake) is a measure of the unbound thyroxine binding globulins in the blood, that is, the TBG that is unsaturated with thyroid hormone. [2] Unsaturated TBG increases with decreased levels of thyroid hormones. It is not directly related to triiodothyronine, despite the name T 3 uptake. [2] Reference ranges:
Thyroxine-binding globulin (TBG) is a globulin protein encoded by the SERPINA7 gene in humans. TBG binds thyroid hormones in circulation . It is one of three transport proteins (along with transthyretin and serum albumin ) responsible for carrying the thyroid hormones thyroxine (T 4 ) and triiodothyronine (T 3 ) in the bloodstream.
Thyroid hormone binding ratio (THBR) is a thyroid function test that measures the "uptake" of T3 or T4 tracer by thyroid-binding globulin (TBG) in a given serum sample. This provides an indirect and reciprocal estimate of the available binding sites on TBG within the sample. The results are then reported as a ratio to normal serum.

T 3 is preferred, because in hypothyroidism T 3 levels may be normal. [84] The ratio of bound to unbound thyroid hormones is known as the thyroid hormone binding ratio (THBR). [85] It is also possible to measure directly the main carriers of the thyroid hormones, thyroglobulin and throxine-binding globulin. [86]
