如果以低血清甲状腺素,甚至以血清促甲状腺素作为甲状腺功做不足的标志,那么老年人较青年人易常发生轻度至中度的甲状腺机能缺陷。大部分自发性甲状腺功能减退(甲减)都是发生在逐渐破坏甲状腺的自身免疫过程,这个过程可以反映在甲状腺淋巴细胞浸润与纤维化以及循环血液中甲状腺抗体水平升高上。 为了确定甲状腺抗体是否可作为老年人甲减的 If low serum thyroxine, or even serum thyrotropin as a sign of thyroid insufficiency, then older people are more prone to mild to moderate hypothyroidism than young people. Most of the spontaneous hypothyroidism (hypothyroidism) occurs in the gradual destruction of the thyroid autoimmune process, the process can be reflected in the thyroid lymphocyte infiltration and fibrosis and circulating blood thyroid antibody levels. To determine whether thyroid antibodies can be used as hypothyroidism in the elderly
