An IGF-1 (insulin-like growth factor 1) blood test measures a hormone that reflects growth hormone activity in the body. It is usually ordered to evaluate growth problems, suspected growth hormone excess or deficiency, or to monitor related treatment.

What it measures

  • IGF-1 (insulin-like growth factor 1) — The main hormone measured; it mirrors average growth hormone levels over recent days.
  • Growth hormone (sometimes) — May be checked alongside IGF-1, though it fluctuates widely through the day.
  • IGFBP-3 (sometimes) — A binding protein that carries IGF-1; can help interpret results in some cases.
  • Related hormone tests — Other hormones may be added by your clinician based on your symptoms.

Who it is for

A clinician such as an endocrinologist, pediatrician, or primary care provider typically orders this test when growth, pituitary, or hormone concerns are being evaluated.

Preparation

Often no fasting is required, but some laboratories prefer a morning sample. Follow the specific instructions from your clinician or lab.

Results and what they mean

Results are reported as a number compared with a reference range for your age and sex. A clinician interprets the value alongside your symptoms and other tests; it is not a diagnosis on its own. This is general information, not medical advice.
