Because thyroid hormones influence metabolism, energy use, and temperature regulation, this panel is commonly used when a clinician suspects an overactive or underactive thyroid.
About Thyroid Blood Testing | Thyroid Level Test in San Leandro
The thyroid is a small, butterfly-shaped gland in the neck that produces hormones regulating metabolism across nearly every organ system.
T4, or thyroxine, is the primary hormone the thyroid releases into the bloodstream. Much of it circulates bound to carrier proteins, while a smaller fraction remains free and biologically active.
T3 uptake is an indirect measure of how much binding capacity is available for thyroid hormones in the blood. It does not measure T3 hormone directly, but it helps estimate how much hormone is unbound and available to tissues.
T7 is a calculated index that combines T4 and T3 uptake results. It provides an adjusted view of circulating thyroid hormone that accounts for protein binding, which can be useful when interpreting T4 values alongside other findings.
