Thyroglobulin Antibodies (TgAb)

Thyroglobulin Antibodies (TgAb) are proteins your immune system produces that mistakenly target thyroglobulin, a protein essential for producing thyroid hormones in the thyroid gland. When these antibodies are present, it can indicate autoimmune thyroid conditions like Hashimoto's thyroiditis or Graves' disease. Elevated TgAb levels may signal that the immune system is attacking the thyroid, potentially leading to thyroid dysfunction. Doctors may test for TgAb to help diagnose thyroid issues, monitor the disease's activity, or assess treatment effectiveness. Their presence helps provide a clearer picture of thyroid health and autoimmune activity.
