Tests to check thyroid function in cases of thyroid diseases such as Graves' disease. Thyroid function tests can be broadly divided into tests of (1) hormone production and secretion, (2) regulatory mechanisms, (3) morphology, (4) hormone action state, and (5) the presence or absence of immune abnormalities. (5) cannot be considered a functional test, but is an important test related to thyroid diseases. (1) Tests of hormone production and secretion These measure the concentration of thyroid hormone in the blood. Most thyroid hormones in the blood are bound to proteins, and so both the bound and free levels are usually measured. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
