Whether or not thyroid peroxidase antibody 700 requires treatment needs to be judged in conjunction with thyroid function and clinical symptoms, and cannot be generalized. The normal value of thyroid peroxidase antibody is usually below 60IU/ml, which may vary from hospital to hospital. If the patient’s thyroid peroxidase antibody is elevated up to 700IU/ml, accompanied by changes in thyroid function, such as symptoms of hypothyroidism such as fatigue, apathy, constipation, loss of appetite, etc., and at the same time there are abnormalities in thyroid-related hormones such as TSH, T3, T4, then the patient needs to take corresponding treatments such as levothyroxine tablets, etc. If the patient only has TPOA, then the patient should be given levothyroxine tablets. If the patient only has an elevated TPOAb of 700IU/ml, and there are no other symptoms or abnormal hormone indexes, treatment is usually not needed, and regular checkups of thyroid hormones in the hospital are sufficient. It is recommended that patients with the above conditions should go to regular hospitals for timely consultation and standardized treatment under the guidance of doctors to avoid delaying their conditions.
