Thyroxine is only one-tenth as potent as triiodothyronine (T3). The free thyroxine index (FTI) is determined by the following calculation: FTI = Thyroxine (T4)/Thyroid Binding Capacity The FTI is a normalized determination that remains relatively constant in healthy individuals and compensates for abnormal levels of binding proteins. Free thyroxine, or free T 4, refers to a type of thyroid hormone in the body that isn’t connected or bound to certain proteins. Many people are also familiar with this term from laboratory testing for thyroid hormone dysfunction. 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).
Is it safe to take a Free Thyroxine test during pregnancy? A free T4 test is considered more accurate than a total T4 test for checking thyroid function. Other names: free thyroxine, free T4, total T4 concentration, thyroxine screen, free T4 concentration What is it used for? A T4 test is used to evaluate thyroid function and diagnose thyroid disease. This test measures the level of free T 4, or free thyroxine, in your blood. A free T 4 test is used to find out how well your thyroid gland is working.

Thyroxine (T4), the principal thyroid hormone, circulates in blood almost completely bound to carrier proteins. However, only the free (unbound) fraction of thyroxine is considered to be biologically active. The main carriers of thyroxine are thyroxine-binding globulin (TBG), pre-albumin and albumin.

It is normal in subjects with high thyroxine-binding globulin hormone binding who are euthyroid (ie, free thyroxine should be normal in nonthyroidal diseases). All free hormone assays should be combined with thyrotropin (thyroid-stimulating hormone) measurements. Free thyroxine (FT4) levels below 0.8 ng/dL indicate possible hypothyroidism. FT4 levels above 2.0 ng/dL indicates possible hyperthyroidism. Neonates can have significantly higher FT4 levels.

Too much or too little T4 can indicate thyroid disease. The T4 hormone comes in two forms: Free T4, which enters the body tissues where it's needed; Bound T4, which attaches to proteins, preventing it from entering body tissues
