About Thyroid Blood Testing | Thyroid Level Test in St. Louis
The thyroid is a small, butterfly-shaped gland in the neck that produces hormones influencing nearly every cell in the body.
Thyroid hormones control how quickly the body uses energy, and they affect heart rate, body temperature, and protein production. When the gland produces too much hormone, the result is hyperthyroidism; when it produces too little, the result is hypothyroidism.
This panel includes three related measurements. T3 uptake estimates how much thyroid hormone is bound to carrier proteins in the blood. T4 measures the total amount of thyroxine, the main thyroid hormone. T7 is a calculated index that combines T3 uptake and T4 to provide a more accurate picture of free thyroxine activity.
Together these values help a healthcare provider assess thyroid function and determine whether further testing or monitoring is needed. Results are typically available within a few business days, and preparation follows the lab's instructions.
