Explanation:
Detailed explanation-1: -The ITT is still regarded as the gold standard for assessing GH reserve. The main second-line test until recently has been the glucagon test. Newer agents include arginine, growth hormone-releasing hormone (GHRH), and growth hormone-releasing peptides (GHRP) such as hexarelin.
Detailed explanation-2: -The insulin tolerance test will assess how much ACTH, cortisol and growth hormone is produced when your body is under stress. This ‘stress’ will be induced by injecting a small amount of insulin to cause a lowering of your blood glucose (hypoglycaemia), under very controlled conditions.
