To exert its effects, T4 is converted to triiodothyronine (T3) by the removal of an iodine atom. In many patients with hypothyroidism or hyperthyroidism, lymphocytes react against the thyroid (thyroid autoimmunity) and make antibodies against thyroid cell proteins. Tg was still undetectable. Thyroid stimulating immunoglobulin or TSI for short (1) is the name of a blood test that is used to identify the presence of autoimmune disease in those with hyperthyroidism. Because T4 contains iodine, the thyroid gland must pull a large amount of iodine from the bloodstream in order to make an appropriate amount of T4. Thyroid hormone supplementation is generally not necessary for the transient hypothyroid phase of subacute thyroiditis unless patients are symptomatic or have clear signs of hypothyroidism. Log-Rank analysis could not determine a relationship between TgAb status and recurrent cancer.
