FT4 (Free Thyroxine)
- Used to judge thyroid function, more sensitive than T4, and the measured value is not affected by TBG
The determination of serum or plasma levels of Thyroxine (T4) is recognized as an important measurement in the assessment of thyroid function. Thyroxine (T4) is one of two major hormones produced by the thyroid gland (the other is called triiodothyronine, or T3), T4 and T3 are regulated by a sensitive feedback system involving the hypothalamus and the pituitary gland. Free T4 is measured together with TSH when thyroid function disorders are suspected. The determination of fT4 is also suitable for monitoring thyrosuppressive therapy.The determination of free T4 has the advantage of being independent of changes in the concentrations and binding properties of the binding proteins
