Thyroglobulin Antibodies
Thyroglobulin antibodies target thyroglobulin, the protein used to store thyroid hormone precursors inside follicles. They are elevated in autoimmune thyroid disease including Hashimoto's thyroiditis and Graves disease. In thyroid cancer patients after thyroidectomy, their presence interferes with thyroglobulin tumor marker measurement and is itself tracked as a surrogate for recurrence.
