Reliable tests for the diagnosis of hyperthyroidism

A reliable test for the diagnosis of hyperthyroidism is a thyroid function test. Thyroid function tests include the detection of thyroid hormone levels in the blood, such as thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), etc. A comprehensive analysis of these indicators can accurately determine the functional status of the thyroid. TSH levels usually decrease significantly during hyperthyroidism, while FT3 and FT4 increase, which is a typical manifestation of hyperthyroidism. In addition, it can also be combined with thyroid autoantibody detection, such as thyroid peroxidase antibody (TPOAb), Thyroglobulin antibody (TgAb), etc., the existence of these antibodies may be related to autoimmune thyroid diseases, which helps to clarify the cause of hyperthyroidism. Thyroid ultrasound also has certain auxiliary diagnostic significance. It can observe the size, shape, structure, etc. of the thyroid gland. It is helpful to determine whether there are nodules, enlargement and other abnormalities in the thyroid gland. Radionuclide scanning for some special types of hyperthyroidism, such as toxic multinodular goiter, can further clarify the functional distribution of thyroid, help to diagnose and formulate treatment plans. In clinical practice, doctors will choose the appropriate combination of examinations according to the specific conditions of patients in order to make an accurate diagnosis and formulate reasonable treatment plans.
