A function test or function test is a diagnostic tool. Endocrinology

The function test is used in endocrinology to test the function of various endocrine glands such as the thyroid or adrenal glands. It can also be tested whether the pituitary gland control is good. Endocrine glands generally separate hormones into the bloodstream that affect the functioning of a tissue or organ in the body. This can be measured by a function test.

During a function test, a hormone, or hormone production substance, is administered to the patient under controlled and standardized conditions. At predetermined times, blood is taken to measure the hormones. Also observed is how the patient responds to this function test, for example, whether the patient is sweating, urine production, etc. If there is a suspicion of a reduced hormone production, the function test will be constructed to give a substance that In healthy people, hormone production will stimulate. In the case of excessive hormone production, the function test will investigate whether this excessive production can be inhibited by administration of a remedy. It can also be checked at which level there is a defect: in the endocrine gland, in the control of the endocrine gland through the brain or that the gland is autonomous.

Examples of function tests are:

Functional testing is performed in a clinical chemical laboratory under the supervision of a physician. The blood collection takes place at standard times after injection of the test substance.
