A Thyroid Antibodies test looks for several types of antibodies which the body develops when a person has an autoimmune disorder. This test looks for Thyroid Peroxidase and Antithyroglobulin antibodies. These antibodies mistakenly target and damage the tissues and proteins of the thyroid gland. The disruption of normal thyroid function this causes can lead to disorders such as Graves Disease or Hashimotos Thyroiditis.
This testing is typically ordered when someone has symptoms of a thyroid disorder or has had irregular results from other thyroid tests such as TSH, T4 and T3. It may also be used when someone has been diagnosed with a thyroid disorder to help monitor their treatment. Pregnant women with an autoimmune disorder often have a Thyroid Antibodies test to help determine if their infant may be at risk for thyroid dysfunction.
