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.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for Thyroglobulin Antibodies. How we verify ranges.
- General guidance, no named sourceUndetectableAny persistent titer marks thyroid autoimmunity
- Lab reference interval<40 IU/mLWhat a lab report flags against. A lab interval is not an optimal target.

Why Thyroglobulin Antibodies matters
Present in autoimmune thyroid disease. Can interfere with thyroglobulin measurement. Elevated in Hashimoto's and thyroid cancer follow-up.
