Antithyroid peroxidase antibodies of 35 IU/ml are usually normal, and the need for treatment depends on the patient’s thyroid function. If the patient has abnormal thyroid function, treatment is needed, but if the patient does not have abnormal thyroid function, no treatment is needed for the time being. The normal range of anti-thyroid peroxidase antibody is <60IU/ml, and anti-thyroid peroxidase antibody of 35IU/ml is within the normal range. Elevated serum anti-thyroid peroxidase antibody titers are seen in autoimmune thyroiditis. Patients with Hashimoto's thyroiditis may have high titers of antithyroid peroxidase antibodies, and patients with Graves' disease may have elevated antibody titers. However, a negative result does not exclude the presence of thyroid autoimmune disease. If the patient has elevated antithyroid peroxidase antibodies and low thyroid hormones, treatment should be initiated with thyroxine as prescribed by the physician. Patients with abnormal antithyroid peroxidase antibodies should go to the hospital in time for a complete examination and regular treatment under the doctor's guidance.
