About Thyroid Blood Testing | Thyroid Level Test in Northbrook
The thyroid is a small gland in the neck that produces hormones influencing nearly every organ system.
Thyroid blood testing typically measures T3 uptake, T4, and a calculated index known as T7. These values help characterize how much thyroid hormone is present and how well it is binding to transport proteins.
T4 is the main hormone released by the thyroid gland, while T3 is the more active form used by cells. T3 uptake is an indirect measure of available binding sites on carrier proteins, and T7 combines T4 with T3 uptake to estimate the free thyroxine index.
Results can suggest hyperthyroidism, in which the gland produces too much hormone, or hypothyroidism, in which it produces too little. Symptoms such as unexplained weight change, fatigue, or temperature sensitivity often prompt this testing.
