Tri iodothyronine (T3) Total Thyroid Blood Test

Why is this test important? This thyroid function blood test measures the amount of Tri-iodothyronine or T3(in your blood. T3 is one of two major hormones produced by the thyroid gland (the other is called Thyroxine, or (T4)). The thyroid is a small, butterfly-shaped gland located just below the Adam's apple.
