The Thyroid Antibody Tests include measurement of antibodies such as Anti-Thyroglobulin (ATG) and Anti-Thyroid Peroxidase (TPO) antibodies (sometimes referred to as AMA in certain panels). These antibodies are produced when the immune system mistakenly attacks the thyroid gland.
The presence of these antibodies is commonly associated with autoimmune thyroid disorders such as Hashimoto’s thyroiditis and Graves’ disease. These conditions can lead to hypothyroidism or hyperthyroidism.
This test is often used alongside thyroid function tests like T3, T4, and TSH to provide a comprehensive evaluation of thyroid health and to confirm autoimmune involvement.
