What is a normal thyroid peroxidase antibody level?
The reference ranges for antithyroid antibodies are as follows: Thyroid peroxidase antibody (TPOAb): Titer less than 9 IU/mLco. Thyroglobulin antibody (TgAb): Less than 116 IU/mL.
What does it mean to have high thyroid peroxidase antibodies?
The presence of TPO antibodies in your blood suggests that the cause of thyroid disease is an autoimmune disorder, such as Hashimoto’s disease or Graves’ disease. In autoimmune disorders, your immune system makes antibodies that mistakenly attack normal tissue.

- After the test.
What is TSH receptor antibody test?
TSH receptor antibody (TRAb) is considered the gold standard diagnostic test for the autoimmunity of Graves’ disease (GD), which is commonly diagnosed clinically.
What antibodies are positive in Graves disease?
In Graves’ disease, the thyroid stimulating antibodies (TRAb) mimic the thyroid stimulating hormone (TSH) secreted by the pituitary gland. This causes the thyroid to continue to produce thyroid hormones, despite the pituitary trying to switch off the thyroid by stopping production of TSH.
What is a high number for thyroid antibodies?
Thyroid Antibody Test Results Normal values are: TPO antibody: Less than 9 IU/mL. Thyroid-stimulating immunoglobulin antibody (TSI): Less than 1.75 IU/L. Anti-Tg antibody: Less than 4 IU/mL.
What does a low TSH receptor antibody mean?
A decrease in the level of TSH receptor antibodies during treatment with antithyroid medications can help determine the chances of the Graves’ disease going into remission. Interestingly, the level TSH receptor antibodies present in an individual falls over time regardless of the type of treatment used.
How can I lower my thyroid antibodies naturally?
Selenium. Studies show that taking 200 mcg of selenium per day may help reduce antithyroid peroxidase (TPO) antibodies and improve well-being in people with Hashimoto’s thyroiditis ( 24 ). Zinc. Zinc is essential for thyroid function.
