Take a IGF 2 Test for Insulin-like growth factor II. IGF 2 is thought to mediate some of the actions of growth hormone (GH). IGF-II is structurally similar to IGF-1 and proinsulin. IGF-2 is secreted by the liver and other tissues and is thought to be involved in building body cells. Plasma levels of IGF-II are dependent upon adequate levels of Human Growth Hormone and other factors, including adequate nutrition. It thought that the interplay of IGF-I and IGF-II modulates tissue growth.
Administration of Human Growth Hormone does not result in increased IGF-2 levels (unlike IGF-I levels, which increase). IGF-II levels decrease in HGH deficiency, malnutrition, and while taking IGF-I.
