ANTI THYROGLOBULIN ANTIBODY

If the Anti TPO autoantibody comes out to be negative but the clinical suspicion of autoimmune thyroid disease is high then one needs to undergo an anti-Tg autoantibody measurement. By detecting these antibodies in the case of neonatal hypothyroidism, the transplacental antibody transfer can be determined. This is useful especially if there is a maternal history of autoimmune thyroiditis.
