Usually, the full name of thyroglobulin antibody is anti-thyroglobulin antibody, and when there is more than 1000IU/ml, it needs to be combined with other indicators to make a comprehensive judgment. Antithyroglobulin antibodies are the main indicator of autoimmune thyroiditis. The normal range of anti-thyroglobulin antibodies should be less than 60IU/ml, and when the value is greater than the normal range, it suggests that the patient may have Hashimoto’s thyroiditis. If the patient’s thyroid hormones are still at normal levels and there are no other symptoms, no special treatment is needed. If the patient’s thyroid hormones are lowered, levothyroxine tablets are usually given as replacement therapy. Patients with thyroglobulin antibodies of 1000IU/ml or more should go to the hospital in time when they experience uncomfortable symptoms, and under the guidance of the doctor, the cause should be clarified and targeted treatment should be given.
