The non-availability of antibody levels (thyroid-stimulating immunoglobulin, TSH receptor antibody, or TPO antibody) to exclude recurrence of her Graves’ disease at her first laboratory assessment while using the nutritional supplement is a fair consideration as a limitation of this case report, but the demonstration of reversibility to normal functions following the discontinuation of the nutritional supplement use is probably a stronger argument. The gene discussed is TPO; the disease is Graves disease.
