Thyroid Hormones and Metabolism
Triiodothyronine (T3) and thyroxine (T4), are tyrosine-based thyroid hormones primarily responsible for the regulation of a number of developmental, metabolic, and neural activities critical for normal physiology. T3 affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate. T4, the prohormone of T3, is the principal hormone produced by the thyroid gland and the major form found in the circulation. Though levels of circulating T3 are much lower than T4 levels, metabolically it is the most active hormone.
Arbor Assays ELISA Kits
The DetectX® Triiodothyronine (T3) ELISA Kit (K056-H1/H5) will measure total T3 in assessment of thyroid gland function or metabolic determination. This assay measures total T3 present in urine, media and extracted serum, plasma or dried fecal samples.
