About fT4
Free thyroxine (fT4) represents the active form of the T4 hormone, which regulates metabolism, growth, and development. Unlike total T4, fT4 is not affected by changes in transport protein concentrations, making it a reliable marker for evaluating thyroid function. It is essential for diagnosing thyroid disorders and monitoring treatment outcomes.
