Thyroglobulin Antibody II (Anti-Thyroglobulin)


Thyroglobulin Antibody II test is a paramagnetic particle, chemiluminescent immunoassay.

Test Utility

Thyroglobulin is produced by the thyroid gland and aids in the storage and synthesis of thyroid hormones. Patients producing autoantibodies to thyroglobulin may have an autoimmune thyroid disease such as Hashimoto’s or Graves’ disease, or a nontoxic goiter. The measurement of the autoantibodies may aid in the diagnosis of such diseases.
