Insulin-like growth factor-I
This test measures the amount of IGF-1 (insulin-like growth factor 1) in your blood. IGF-1 is a hormone, a chemical messenger in your bloodstream that controls the actions of certain cells or organs. IGF-1 manages the effects of growth hormone (GH) in your body. Together, IGF-1 and GH promote normal growth of bones and tissues.
