What is IGF-1 test?

This test measures the amount of IGF-1 (insulin-like growth factor 1) in your blood. IGF-1 is a hormone that manages the effects of growth hormone (GH) in your body. Together, IGF-1 and GH promote normal growth of bones and tissues.

What is the function of IGF2?

It is believed to be a major fetal growth factor in contrast to Insulin-like growth factor 1, which is a major growth factor in adults. In humans, the IGF2 gene is located on chromosome 11p 15.5, a region which contains numerous imprinted genes.

What is insulin-like growth factor (IGF-1)?

^ a b Laron Z (October 2001). Insulin-like growth factor 1 (IGF-1): a growth hormone. Molecular Pathology. 54 (5): 311–6. doi: 10.1136/mp.54.5.311. PMC 1187088. PMID 11577173. ^ Martin D, Nguyen Q, Molinolo A, Gutkind JS (May 2014).

What is the pathophysiology of IGF production?

Production is stimulated by growth hormone (GH) and can be retarded by undernutrition, growth hormone insensitivity, lack of growth hormone receptors, or failures of the downstream signaling pathway post GH receptor including SHP2 and STAT5B. Approximately 98% of IGF-1 is always bound to one of 6 binding proteins (IGF-BP).

What is the function of IGF 1?

IGF-1 is a hormone found naturally in your blood. Its main job is to regulate the effects of growth hormone (GH) in your body. Normal IGF-1 and GH functions include tissue and bone growth. IGF-1 is formed in different tissues as a result of GH in the blood.

What is the insulin-like growth factor-1 (IGF-1) test?

The insulin-like growth factor-1 (IGF-1) test is an indirect measure of the average amount of growth hormone (GH) being produced by the body. IGF-1 and GH are peptide hormones which are small proteins made up of a small chain of amino acids. IGF-1 and GH are vital for normal bone and tissue growth and development.

How accurate are IGF-1 levels in a blood test?

Since GH levels vary throughout the day, IGF-1 concentrations are a reflection of average GH production, not of the actual amount of GH in the blood at the time of sampling. This is accurate up to the point at which the liver’s capacity to produce IGF-1 is reached.

What is the difference between IGF1 and GH?

GH is produced by the pituitary gland, a grape-sized gland which sits at base of the brain behind the bridge of your ... The insulin-like growth factor-1 (IGF-1) test is an indirect measure of the average amount of growth hormone (GH) being produced by the body.

What is insulin-like growth factor-1 (IGF-1)?

Insulin-like growth factor-1 (IGF-1 or IGF) is a hormone your liver makes. One of its main jobs is to tell your bones and muscles to grow. It’s in the same family as the hormone insulin and acts a lot like it.

What does IGF 1 mean on blood test?

IGF, IGF-1 This test measures the amount of insulin-like growth factor-1 (IGF-1) in your blood. IGF-1 is a hormone found naturally in your blood. Its main job is to regulate the effects of growth hormone (GH) in your body. IGF-1 is formed in different tissues as a result of GH in the blood.

How is IGF-1 produced?

Production is stimulated by growth hormone (GH). Most of IGF-1 is bound to one of 6 binding proteins (IGF-BP). IGFBP-1 is regulated by insulin. IGF-1 is produced throughout life; the highest rates of IGF-1 production occur during the pubertal growth spurt. The lowest levels occur in infancy and old age.

What is the binding protein for IGF 1?

Most of IGF-1 is bound to one of 6 binding proteins (IGF-BP). IGFBP-1 is regulated by insulin. IGF-1 is produced throughout life; the highest rates of IGF-1 production occur during the pubertal growth spurt. The lowest levels occur in infancy and old age.
