Anti-thyroid peroxidase antibody 1300IU/ml , how it needs to be treated, needs to be combined with thyroid function. Hypothyroidism can be treated with medications such as levothyroxine sodium tablets. Antithyroid peroxidase antibody of 1300IU/ml indicates the presence of immune inflammation, and when the antibody is elevated, it causes some damage to the body’s thyroid tissues, and abnormalities in thyroid function may occur. If anti-thyroid peroxidase antibodies or anti-thyroglobulin antibodies are elevated, it is recommended to check the thyroid function to understand the condition, and choose a treatment plan according to the different conditions. If there is no abnormality in thyroid function, no special treatment is needed, and regular checkups are sufficient; if there is hyperthyroidism, with symptoms such as trembling hands and mental hyperactivity, medications such as methimazole or propylthiouracil can be given, and symptomatic treatment with iodine 131 can be given if necessary; if hypothyroidism is present, levothyroxine sodium tablets can be considered for replacement therapy. If the anti-thyroid peroxidase antibody reaches 1300IU/ml, it is necessary to consult the endocrinology department for treatment under the guidance and advice of the doctor.
