Description
Triiodothyronine (T3) and thyroxine (T4) are two major hormones produced by the thyroid gland. Together they help control the rate at which the body uses energy.
Almost all of the T3 and T4 found in the blood is bound to protein. The rest is free (unbound) and is the biologically active form of the hormone. If the thyroid gland produces excessive amounts of T4 and T3, then the person affected may have symptoms associated with hyperthyroidism, and if the thyroid gland produces insufficient amounts of thyroid hormones, then the person may have signs and symptoms associated with hypothyroidism
Requirements: Certain medications can interfere with the free or total T3 test (Please consult your physician).
