Differential diagnosis

Differential diagnosis

Clinically, there are some inflammatory hyperthyroidism (or destructive hyperthyroidism), which is caused by thyroid inflammatory reaction leading to changes in thyroid follicular cell membrane permeability. A large amount of thyroid hormone is released into the blood cells in the cells, causing obvious thyroid hormone in the blood. Elevation and decreased TSH, clinical manifestations and biochemical tests resemble hyperthyroidism. Inflammatory hyperthyroidism includes hyperthyroidism, hyperthyroidism, hyperthyroidism, hyperthyroidism, postpartum thyroiditis, and iodine-induced hyperthyroidism. It is important to identify Graves' disease and inflammatory hyperthyroidism because the former requires active treatment and the latter does not require treatment. The biggest difference between the two is the thyroid 131I rate test, the former thyroid 131I rate is elevated or normal, the latter is inhibited; in addition, the former TRAb is positive, the latter is negative; the former combined with thyroid-related eye disease The latter does not incorporate thyroid-associated eye disease.
