Part Descriptions

LP15900-1   Thyroxine
The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosine (monoiodotyrosine) and the coupling of iodotyrosine (diiodotyrosine) in thyroglobulin. Thyroxine is separated from thyroglobulin by proteolysis and released in the blood. Thyroxine is peripherally deiodinated to form triiodothyronine which exerts broad stimulatory effects on cell metabolism. Source: National Library of Medicine, MeSH 2006

LP40008-2   Thyroxine Ab
Patients with autoimmune thyroid disease (ATD), including Hashimoto's thyroiditis and Grave's disease, occasionally develop autoantibodies to T4 and T3. These autoantibodies interfere with the measurement of T4 and T3 by immunoassay. Thus, abnormal or disparate T4 concentrations may be due to autoantibodies.
