Anti-thyroid peroxidase antibody, which is 318 IU/ml , the need for treatment is determined in relation to thyroid function. If hypothyroidism is present, treatment is required under the supervision of a doctor. Anti-thyroid peroxidase is an autoimmune antibody that acts mainly on the enzyme thyroid peroxidase, which can affect the synthesis of thyroxine, thus affecting thyroid function. It is mainly found in diseases such as hypothyroidism and Hashimoto’s thyroiditis, and may also be elevated by certain autoimmune diseases such as rheumatoid diseases and systemic lupus erythematosus. When the antibody is elevated, the thyroid function should be checked regularly in the endocrinology department. If hypothyroidism occurs, levothyroxine sodium tablets can be taken under the guidance of a physician, and if there is no obvious change in the thyroid function, regular checkups will be sufficient.
