Insulin-like Growth Factor 1 (IGF-1)


Insulin-like growth factor 1 (IGF-1, a.k.a. somatomedin C) is a marker of growth hormone (GH) secretion. Due to GH’s short half-life in the body, blood testing for IGF-1 is a more reliable indicator of GH levels than testing for GH itself.

Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is primarily produced by the liver as an endocrine hormone and plays an influential role in virtually every system from muscle, bone, and connective tissue growth and repair, to the selective regulation of various aspects of metabolism, as well as helping maintain normal brain function and cardiac health.


Fasting is not required for this test. Take all medications as prescribed.
