About Free T4 Levels Test | Thyroid Testing (FT4) in Fallbrook
The Free T4 Levels Test evaluates the amount of unbound thyroxine in the blood to help assess thyroid function.
Thyroxine, or T4, is one of the two primary hormones produced by the thyroid gland. Most T4 in the blood is attached to transport proteins, while a smaller portion remains free and biologically active.
Because only the free portion can enter tissues and influence metabolism, measuring free T4 gives a more direct view of thyroid activity than measuring total T4 alone.
Clinicians may order a free T4 test when symptoms or other lab results suggest an overactive or underactive thyroid. It is frequently interpreted alongside TSH and sometimes free T3 to build a fuller picture of thyroid status.
