The normal value of thyroid receptor antibody should be less than 15 U/L. It is secreted by the body’s pituitary gland and acts mainly on the thyroid gland, which can target the hormones of the thyroid gland and perform negative adjustment effects. If the level of this substance is elevated, it indicates that the amount of hormones secreted by the thyroid gland is reduced and can easily cause hypothyroidism. Conversely, if the level of thyroid stimulating hormone receptor antibodies is reduced, the patient may have hyperthyroidism. Currently, there are relatively more clinical tests for hyperthyroidism with this substance. After the test, routine blood tests and other imaging laboratory tests can be performed to aid in the diagnosis, followed by treatment with medications, such as methimazole, or simultaneous iodination, both of which work better with each other.
