| Thyroglobulin antibodies should be measured by quantitative assays (RIA, IRMA, ELISA) and are detected in about 60 to 70% of patients with autoimmune thyreoditis and in 20 to 40% of Graves' patients. Because of a lower sensitivity compared to TPO antibodies their value is limited and we do not advocate their use as a routine primary tool in diagnosing autoimmune thyroid disease. |
