Thyroid Hormone Kinetics

Meaning

Thyroid hormone kinetics refers to the study of the rates and processes governing the absorption, distribution, metabolism, and excretion (ADME) of the thyroid hormones, T4 and T3, within the body. This includes the precise conversion of the prohormone T4 into the active T3 in peripheral tissues, which is a crucial determinant of cellular metabolic rate and function. Understanding these dynamic processes is essential for accurately diagnosing and managing thyroid disorders and optimizing replacement therapy.
