Anti-Thyroglobulin (Anti-TG) Antibodies Test in Serum

Anti-Thyroglobulin (Anti-TG) antibodies test is a blood test that measures the levels of antibodies against the protein thyroglobulin in the serum. Thyroglobulin is a protein produced by the thyroid gland, which is essential for the production of thyroid hormones T3 and T4. Sometimes, the immune system mistakenly identifies thyroglobulin as a foreign substance and produces antibodies against it. The presence of anti-TG antibodies can indicate an autoimmune disorder affecting the thyroid gland, such as Hashimoto’s thyroiditis or Graves' disease.
