Thyroglobulin antibody 317IU/ml is not normal. Thyroglobulin antibodies should normally be less than 60 IU/ml. Due to different testing methods and reagents, the reference indexes vary from hospital to hospital and need to be analyzed specifically. Thyroglobulin antibodies are thyroid autoantibodies used to help diagnose autoimmune thyroid disease. Elevated thyroglobulin antibodies can be seen in Hashimoto’s thyroiditis and Graves’ disease. Patients who find thyroglobulin antibodies of 317IU/ml should go to the hospital in time to improve the relevant examinations and be evaluated by a professional doctor for treatment, so as to avoid delaying the condition, which may cause serious HO.
