Anti-thyroglobulin antibody (ATGA)

An antibody raised against thyroglobulin. ATG's target antigen thyroglobulin (TG) is a soluble iodinated glycoprotein synthesized and secreted by thyroid epithelial cells, with a molecular weight of 660 kD and consisting of 2748 amino acids. It is a biosynthetic precursor of T3 (triiodothyronine, triiodothyronine), T4 (tet-raiodothyronine, tetrathymidine, thyroxine, thyroxine), which is mainly stored in colloidal form in thyroid filtration. In the vesicle, the content of normal human serum is extremely small (10-40 ng/ml). Witebsky et al. immunized rabbits with the same thyroid tissue to induce thyroiditis in rabbits similar to ATG and Hashimoto's thyroiditis. ATG is the most typical organ-specific antibody among various autoantibodies in humans.

Clinical significance Positive in chronic lymphocytic thyroiditis, hyperthyroidism, primary hypothyroidism, certain liver diseases, various collagen diseases, myasthenia gravis, and some normal women. Precautions It has also been reported that 2% to 5% of normal people (mostly women) can detect ATG. Inspection process Indirect immunofluorescence. Not suitable for the crowd There are no taboos.
