High anti-thyroglobulin antibodies indicate that the patient may have a condition such as Hashimoto’s thyroiditis (chronic lymphocytic thyroiditis) or diffuse toxic goiter (Graves’ disease). Antithyroglobulin antibodies are thyroid autoantibodies that are used to help diagnose autoimmune thyroid disease. Antithyroglobulin antibodies are of clinical value in the treatment of thyroiditis, especially Hashimoto’s thyroiditis. Antithyroglobulin antibodies should be less than 60 IU/ml under normal conditions. If anti-thyroglobulin antibodies are found to be higher than normal, it is necessary to pay attention to them and seek medical treatment in time to avoid delaying the condition, which may lead to serious consequences.
