Despite its relatively small size, it produces hormones that affect every cell, tissue, and organ in the human body. The thyroid gland produces two types of hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid hormones are two hormones produced and released by the thyroid gland, namely triiodothyronine (T 3) and thyroxine (T 4).They are tyrosine-based hormones that are primarily responsible for regulation of metabolism.T 3 and T 4 are partially composed of iodine.A deficiency of iodine leads to decreased production of T 3 and T 4, enlarges the thyroid tissue and will cause the disease known "thyroxine free ft4 is low, what does this mean?" Answered by Dr. Quang Nguyen: Low thyroid: It means that your thyroid level is possibly low. You ne THYROXINE (T4), FREE: Free thyroxine comprises a small fraction of total thyroxine. The free T4 (FT4) is available to the tissues and is, therefore, the metabolically active fraction.

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.

2021-02-07 Objective: To determine whether a difference exists in the free thyroxine level required to achieve a normal thyrotropin (thyroid-stimulating hormone or TSH) level between patients with primary hypothyroidism and euthyroid control subjects and compare the free thyroxine levels in patients with primary and secondary hypothyroidism receiving thyroid hormone replacement. Interpretation. 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. Standardization of Free Thyroxine Measurements Allows the Adoption of a More Uniform Reference Interval Clin Chem. 2017 Oct;63(10):1642-1652.
