Order Thyroid Blood Testing | Thyroid Level TestThyroid blood testing measures circulating thyroid hormones to assess how well the thyroid gland is functioning. The thyroid produces hormones that regulate metabolism, heart rate, body temperature, and energy use. When levels drift outside their reference ranges, the resulting patterns help clinicians distinguish an overactive thyroid from an underactive one.
About Thyroid Blood Testing | Thyroid Level Test in Walnut
This panel reports three related values: T3 uptake, T4, and T7.
T4, or thyroxine, is the main hormone secreted by the thyroid gland. A total T4 measurement reflects the amount of thyroxine in the bloodstream, most of which travels bound to carrier proteins.
T3 uptake is an indirect measure of how many binding sites on those carrier proteins remain available. It does not measure the hormone triiodothyronine (T3) directly; instead, it helps estimate how much thyroxine is unbound and therefore free to act on tissues.
T7, sometimes called the free thyroxine index, is a calculated value derived from the T4 result and the T3 uptake result. It provides an adjusted estimate of free thyroxine that corrects for variations in binding-protein levels, which can shift total hormone readings without any true change in thyroid status.
