Whether high thyroglobulin antibodies are serious or not needs to be judged in combination with thyroid function, thyroid ultrasound and other conditions. If there are no obvious symptoms and no change in thyroid function, it is generally not important; if there is a combination of malignant thyroid disease, it is important. If thyroglobulin antibodies are elevated, further examination of thyroid function, thyroid ultrasound and, if necessary, thyroid pathology are recommended. 1. If the thyroglobulin antibodies are simply elevated and all other tests are normal, there is no need for special treatment, and regular checkups will be sufficient, so it does not matter. 2. If hypothyroidism is suggested, it is necessary to take levothyroxine sodium tablets for replacement therapy, and it is generally not important after active treatment. 4. If hyperthyroidism is indicated, anti-thyroid medication, radioactive iodine therapy and surgery are needed to stabilize the thyroid function, which is generally not important. 5. If thyroid ultrasound suggests the possibility of malignant lesions, it is necessary to do a pathological examination, and if necessary, surgical treatment, which is usually important. Thyroglobulin antibodies are high, it is recommended to go to endocrinology department for further consultation.
