Test Usage

The action of human growth hormone (HGH) from the pituitary is mediated through IGF-1 which is formed in the liver. As well as its effects on growth, it has insulin-like actions. IGF-1 synthesis is suppressed by malnutrition as well as HGH deficiency.

IGF-1 and HGH are measured in suspected acromegaly and in pituitary dwarfism.
