About Free T4 Levels Test | Thyroid Testing (FT4) in Eagle Mountain
Thyroxine, often abbreviated as T4, is one of the two primary hormones produced by the thyroid gland.
Most thyroxine in the blood is bound to transport proteins, which leaves only a small fraction free to enter cells and exert effects. The free T4 test isolates and quantifies that unbound fraction.
Physicians order free T4 testing to evaluate thyroid function when symptoms suggest an overactive or underactive thyroid, or when an earlier screening test such as TSH returns an abnormal result.
Results are typically interpreted alongside TSH and sometimes free T3, since the interplay among these markers helps distinguish different patterns of thyroid dysfunction.
