About Thyroid Blood Testing | Thyroid Level Test in San Juan

This panel reports three related values: T3 uptake, T4, and T7. Together they offer a broad view of thyroid hormone activity in the bloodstream.

T3 uptake is an indirect measure that reflects how much thyroid hormone is available to bind with carrier proteins in the blood. It is not a direct measurement of triiodothyronine (T3) itself, but it helps estimate the amount of free, unbound hormone.

T4 refers to thyroxine, the main hormone produced by the thyroid gland. Most T4 circulates attached to proteins, while a smaller fraction remains free and biologically active. Total T4 and related calculations can indicate whether the gland is producing too much or too little hormone.

T7 is a calculated index derived from T3 uptake and T4 results. It is sometimes called the free thyroxine index and provides an adjusted estimate of circulating thyroxine. Clinicians interpret these values alongside symptoms and other findings to help distinguish hyperthyroidism from hypothyroidism.
