What is Aglobulin ntithyroantibody ?

Thyroglobulin is a key protein in the thyroid gland that is essential for the synthesis of thyroxine (T4) and triiodothyronine (T3). Aglobulin ntithyroantibody test measures levels of antibodies produced against thyroglobulin. This test helps to identify autoimmune diseases involving the thyroid gland. The presence of thyroid autoantibodies causes disorders such as Hashimoto’s thyroiditis, Graves’ disease, Hypothyroidism, Thyroid cancer, etc. Women with high levels of ATG might face complications like miscarriages or infertility. While in cases of neonatal hypothyroidism, the detection of ATG in the infant suggests transplacental antibody transfer, particularly if the mother has a history of autoimmune thyroiditis or detectable thyroid autoantibodies.
