T3 Levels

Meaning

T3 Levels refer to the measurable concentration of Triiodothyronine, the most biologically active thyroid hormone, circulating in the blood or available to peripheral tissues. This hormone is crucial for regulating basal metabolic rate, body temperature, and the function of nearly every cell type in the body, including the heart and brain. Assessing both free and total T3 levels is vital for accurately diagnosing and managing thyroid-related metabolic and energy disorders.
