The thyroid gland, situated in the neck, produces the hormones Thyroxine (T4) and Tri-iodothyronine (T3). Thyroid function tests (TFTs) include measuring the amount of T4 or T3 and the pituitary hormone, Thyroid Stimulating Hormone (TSH) in your blood. These hormones are chemical substances that travel through the bloodstream and control or regulate how fast your body uses energy.
