Test Code

Antithyroglobulin Antibodies (ATG) are immune proteins produced when the body’s immune system mistakenly attacks thyroglobulin, a protein essential for thyroid hormone production. The presence of ATG indicates an autoimmune response affecting the thyroid gland.

This test is commonly used to diagnose and monitor autoimmune thyroid diseases such as Hashimoto’s thyroiditis and Graves’ disease. It is also helpful in evaluating unexplained thyroid dysfunction and in the follow-up of thyroid cancer patients after thyroidectomy, as antibodies can interfere with thyroglobulin measurements. ATG results are interpreted along with thyroid hormone levels, TSH, and other thyroid antibody tests for accurate clinical assessment.
