About Thyroid Blood Testing | Thyroid Level Test in Cary
The thyroid is a small, butterfly-shaped gland in the neck that produces hormones influencing nearly every organ system.
T4, or thyroxine, is the main hormone the thyroid releases into circulation. Most of it travels bound to carrier proteins, leaving only a small fraction free to act on tissues.
T3 uptake is an indirect measure of how much binding capacity remains available on those carrier proteins. It does not measure T3 hormone itself, despite the name.
The T7 index, sometimes called the free thyroxine index, combines T4 and T3 uptake results into a single value. This calculation helps correct for shifts in binding proteins and offers a clearer estimate of the active hormone available to the body.
