SANTIAGO-PENA, Luis Francisco. Thyroid Physiology. Disfunction and laboratory tests in thyroid diseases. Rev. ORL [online]. 2020, vol.11, n.3, pp.253-257.  Epub 11-Ene-2021. ISSN 2444-7986.  https://dx.doi.org/10.14201/orl.21514.

The study of functional thyroid pathology requires an adequate knowledge of the processes involved in the synthesis, secretion, transport, metabolism and regulation and mechanism of action of thyroid hormones In the initial management of thyroid dysfunction, the interpretation of the values of Thyrotropin (TSH) and peripheral hormones (free T4 and T3) will let us know if the etiology is in the thyroid or outside the thyroid.

Palabras clave : thyroid function tests; thyrotropin; thyroid hormone metabolism; thyroid hormone receptor; thyroxine; triiodothyronine.
