704354

CPT code:

86800

Synonyms:

Antithyroglobulin Antibody

Clinical Use:

Detect and confirm autoimmune thyroiditis, Hashimoto thyroiditis

Test Information:

diagnosed with disseminated thyroid carcinoma (~20%). It has been suggested that low levels may represent “natural” antibody in healthy individuals or, alternatively, may represent underlying silent autoimmune thyroid disease. There is some debate over the clinical utility of serum TgAb measurement for assessing the presence of thyroid autoimmunity in areas of iodide sufficiency. In iodide-deficient areas, however, TgAb is believed to be useful for detecting autoimmune thyroid disease, especially for patients with a nodular goiter. TgAb measurements are also useful for monitoring iodide therapy for endemic goiter, since iodinated Tg molecules are more immunogenic. Sera samples were obtained in the United States for males <30 years of age following the criteria outlined by the National Academy of Clinical Biochemists (NACB) for establishing a normal reference range for thyroid tests. The screening criteria included serum TSH levels between 0.5 and 2.0 mIU/L, no personal or family history of thyroid disease, and absence of nonthyroid autoimmune disease. One hundred thirty-seven screened samples were tested, generating a 95% nonparametric upper reference limit below 4 IU/mL. Additionally, 519 samples were collected in the United States for both males and females ranging from 18 to 74 years of age. The screening criteria included serum TSH levels between 0.5 and 2.0 mIU/L, no personal or family history of thyroid disease, and absence of nonthyroid autoimmune disease. Of the 519 samples tested, 96% fell below 4 IU/mL.
