Description

LP39996-1   Thyroglobulin Ab
Circulating immunoglobulins directed against thyroglobulin are commonly present in patients with autoimmune (Hashimoto) thyroiditis and, to a lesser extent, Graves disease. Thyroglobulin is a 660-kd protein precursor of thyroid hormones. Thyroglobulin antibodies are present in the sera of approximately 70% of patients with autoimmune thyroiditis. The principal use of the test is to confirm that a patient's diffuse goiter and/or hypothyroidism is due to autoimmune thyroiditis. The test may also help distinguish Graves disease from toxic nodular goiter. Although thyroglobulin antibodies are present less often than thyroid microsomal antibodies (eg, thyroid peroxidase antibodies, anti-TPO) in patients with autoimmune thyroid diseases, screening fro both immunoglobulins increases diagnostic sensitivity. Thyroglobulin antibodies may be detected in individuals without clinically significant thyroid disease. They do not define the patient's thyroid functional status.
