About This Test
The Free triiodothyrine (T3) test measures the amount of this hormone in the blood. Whenever T3, T4 and TSH fails to give a clear diagnostic picture, it is advisable to do FT3,FT4 tests. Especially when patient is on treatment or pregnant free hormones gives a better picture. FT3 is carried out to diagnose hyperthyroidism, to determine thyroid function and to help monitor the progress of a person with a thyroid disorder. Triiodothyronine (T3) is a thyroid hormone bound to carrier proteins that circulates in blood. The main transport protein is thyroxin binding globulin (TBG). The free (unbound) portion of triiodothyronine (free T3) is responsible for the biological action and plays an important role in the body’s control of metabolism. Free Triiodothyronine test measures the amount of T3 in the blood. Blood levels of T3 is increased or decreased because of insufficient or excessive production of the hormone by the thyroid gland due to thyroid dysfunction or pituitary dysfunction. Abnormal levels of T3 in the blood are associated with hyperthyroidism, hypothyroidism, and slow metabolism.
