Order Thyroid Blood Testing | Thyroid Level TestThyroid Blood Testing measures three related values—T3 uptake, T4, and T7—to help assess how well the thyroid gland is functioning. Because thyroid hormones influence metabolism, energy use, and many organ systems, these results are often used when a clinician is evaluating symptoms that could point to an overactive or underactive thyroid.
About Thyroid Blood Testing | Thyroid Level Test in Bellflower
The thyroid is a small, butterfly-shaped gland in the neck that produces hormones regulating metabolism.
Thyroid hormones triiodothyronine (T3) and thyroxine (T4) circulate in the blood, mostly bound to carrier proteins, with a smaller free fraction available to act on tissues.
T3 uptake is an indirect measure of how much binding capacity is available on those carrier proteins; it does not directly quantify T3 hormone. T4 reflects the total amount of thyroxine present, and T7 is a calculated index derived from T3 uptake and T4 that estimates the free thyroxine level.
When the thyroid produces too much hormone, the condition is called hyperthyroidism; when it produces too little, it is called hypothyroidism. A thyroid blood test can support the diagnostic process, though results are interpreted alongside symptoms and other clinical findings.
