The report of hyperthyroidism includes the following aspects, which can be analyzed from different perspectives: 1. thyroid function results. The results of thyroid function show elevated levels of thyroid hormones and decreased levels of thyrotropic hormones, which are typical of primary hyperthyroidism. 2. Levels of thyroid-related antibodies. In general, if the level of thyroid-related antibodies is elevated, the cause of hyperthyroidism is considered to be due to autoimmune factors, i.e. autoantibody tests are performed to clarify the cause of hyperthyroidism. 3. Ultrasound of the thyroid gland. If the ultrasound of the thyroid gland shows an increase in the size of the diffuse thyroid gland with very rich blood flow during the diagnosis of hyperthyroidism, there are more reasons to consider toxic diffuse goiter.
