The indicators of hyperthyroidism mainly include several aspects: 1. Thyroid function indicators: These include T3 and T4 secreted by the thyroid gland, and in some hospitals, they include total T3, total T4, free T3 and free T4, which are elevated in hyperthyroidism. In addition to this, thyroid stimulating hormone, TSH, secreted by the pituitary gland is also included. 2. Thyroid-related antibodies: These include TPO antibodies, TG antibodies, TSH receptor antibodies, etc. These indicators usually reflect thyroid etiology. The most common cause of hyperthyroidism is an autoimmune reaction. If these antibodies are high, it suggests that the patient has an autoimmune reaction of his own, and the hyperthyroidism may be considered a diffuse toxic goiter. These antibodies are not treated with specific drugs, but only reflect the autoimmune reaction process. 3. Other tests: In addition to the blood-related tests mentioned above, ultrasound examination of the thyroid gland is included to assess the shape and size of the thyroid gland, the presence of nodules and cysts, and the presence of other problems.
