Thyroid Hormone Status

Meaning

The comprehensive clinical and biochemical evaluation of the functional state of the thyroid axis, encompassing the circulating levels of Thyroid Stimulating Hormone (TSH), free and total thyroxine (T4), and free and total triiodothyronine (T3). This status reflects the body’s overall metabolic rate and energy utilization, as thyroid hormones are master regulators of cellular metabolism across virtually all tissues. A full status assessment is vital for diagnosis.
