The thyroid gland produces and secretes T4, otherwise known as thyroxine. Proteins bind to T4 and carry it throughout the bloodstream. Once in the tissues, T4 is released from the proteins and is now free to convert into the more active form called T3. 2021-02-07 2019-03-25 thyroxine (T4) [thi-rok´sin] a thyroid hormone that contains iodine and is a derivative of the amino acid tyrosine, occurring naturally as l-thyroxine; its chemical name is tetraiodothyronine. It is formed and stored in the thyroid follicles as thyroglobulin and released from the gland by the action of a proteolytic enzyme.

The test to measure unbound levels of thyroxine is usually called a free thyroxine or free T 4 test. Free T 4 may be indicated when binding globulin (TBG) problems are perceived, or when conventional test results seem inconsistent with clinical observations. It is normal in subjects with high thyroxine-binding globulin hormone binding who are euthyroid (ie, free thyroxine should be normal in nonthyroidal diseases).

Free and total thyroxine (fT4 and T4): when to perform the analysis. Free and total thyroxine (fT4 and T4) they are measured to evaluate thyroid function and identify any alterations due to both reduced thyroid function (hypothyroidism) and increased thyroid function (hyperthyroidism); measuring the T4 and fT4 values is also useful for monitoring the appropriateness of thyroid hormone Free thyroxine (free T4) tests are used to help evaluate thyroid function and diagnose thyroid diseases, including hyperthyroidism and hypothyroidism, usually after discovering that the thyroid stimulating hormone (TSH) level is abnormal. Most of the T4 and T3 circulate in the blood bound to protein, while a small percentage is free (unbound). Background: The IFCC Committee for Standardization of Thyroid Function Tests intended to standardize free thyroxine (FT 4) immunoassays. We developed a Système International d'Unités traceable conventional reference measurement procedure (RMP) based on equilibrium dialysis and mass spectrometry. A free T4 test measures only thyroxine that's not bound to proteins. Many doctors today use the free T4 test because it's more accurate than the test for bound T4. The T4 test can also detect problems with your pituitary gland.
