What the heck are Thyroglobulin Antibodies

Thyroglobulin antibodies are antibodies that recognize and bind to thyroglobulin, interfering with its function.

Thyroglobulin antibodies are antibodies that recognize and bind to thyroglobulin, interfering with its function. Thyroglobulin is critical for thyroid hormone production, so thyroglobulin antibodies usually indicate thyroid disease. The thyroglobulin antibodies test is usually ordered after thyroid abnormalities have been detected with some other testing, such as TSH (Thyroid-Stimulating Hormone) and FREE T4. It is ordered along with the Thyroid Peroxidase (TPO) Antibodies test. Thyroglobulin Antibodies (TgAb), attack thyroglobulin, which your thyroid uses to produce its hormones. They are typically elevated in Hashimoto’s patients.

Optimal reference range for Thyroglobulin Antibodies:

<4.0 IU/mL
