Insulin hypoglycemic GH, ACTH test

Insulin hypoglycemic GH and ACTH tests are performed by the following principles. Hypoglycemia is a very strong stress factor for the hypothalamus-pituitary. In normal people, when the blood glucose drops below 2.2mmol / L, the secretion of GH, ACTH-cortisol, TSH and catecholamine is significantly excited. This test uses a standard amount of insulin to cause hypoglycemia to measure the reserve function of GH, and also measures the function of the pituitary-adrenal axis and pituitary-thyroid axis.
