The IGF-1 (Insulin-Like Growth Factor 1) test measures the level of IGF-1, a hormone produced mainly by the liver in response to growth hormone (GH). IGF-1 reflects average growth hormone activity and is more stable throughout the day than GH itself.
This test is commonly used to evaluate growth hormone disorders, including growth hormone deficiency or excess, and to assess pituitary function. It may be ordered in children with growth concerns or in adults with unexplained fatigue, changes in body composition, or suspected pituitary disorders.
