About Thyroid Blood Testing | Thyroid Level Test in Federal Way
This panel reports three related values: T3 uptake, T4, and T7. Together they offer a broad view of thyroid hormone production and binding.
T4, or thyroxine, is the primary hormone secreted by the thyroid gland. It circulates largely bound to transport proteins, with a smaller free fraction available to act on tissues.
T3 uptake is an indirect measure of how much thyroid hormone is bound to carrier proteins in the blood. It does not measure the hormone triiodothyronine directly, despite the similar name.
The T7 index is a calculated value derived from T4 and T3 uptake. It estimates the amount of free thyroxine available to the body and helps clarify results when binding proteins are abnormal.
