Thyroglobulin Antibodies
Clinical Use
Order TestUse
Thyroglobulin Antibodies (TgAb) are measured to assess for autoimmune thyroid disease such as Hashimoto’s thyroiditis and Graves’ disease. Their presence may interfere with thyroglobulin measurement, particularly in the context of thyroid cancer monitoring, making TgAb testing clinically important to ensure accurate interpretation of thyroglobulin levels.
