Elevated Thyroglobulin (Tg) concentrations have been reported in different thyroid conditions like Hashimoto’s disease, Graves’ disease, thyroid adenoma, and thyroid carcinoma. The determination of Tg can also be helpful to distinguish between subacute thyroiditis and factitious thyrotoxicosis. In cases of congenital hypothyroidism the determination of Tg can be used to differentiate between the complete absence of the thyroid gland and thyroid
hypoplasia or other pathological conditions.
