Autoimmune Thyroiditis

Thyroiditis is an inflammation of the thyroid gland and has multiple etiologies, including chronic (Graves’ disease and Hashimoto thyroiditis), silent or subclinical thyroiditis, transient hyperthyroidism, subacute, and acute. Laboratory testing is used to differentiate autoimmune-mediated thyroid disease from other etiologies and includes thyroid stimulating hormone (TSH) followed by free thyroxine (T4). Depending on results, antibody screening may also be necessary. Antithyroid antibody tests include thyroid peroxidase (TPO), TSH receptor antibodies (TRAb), and antithyroglobulin antibodies (Tg).
