Expanding the scope to include thyroid antibody measurements, such as thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb), to better understand the interplay between iodine concentration, thyroid autoimmunity, and thyroid function could also provide deeper insights into the relationship between iodine concentration and thyroid function, further enhancing the clinical utility of CT imaging in thyroid health assessment. The gene discussed is TG; the disease is autoimmune thyroid disease.
