A blood test to measure the level of IGF-BP3, the Insulin-like growth factor binding protein 3.
The IGF binding protein 3 (IGFBP-3) is a protein that binds to insulin-like growth factor (IGF) and regulates its activity. This test measures the level of IGFBP-3 in the bloodstream. It's important for assessing growth hormone function and overall health. Results help understand potential growth hormone deficiencies or excesses. This test is useful for monitoring growth and development, particularly in children and adolescents, and for diagnosing certain medical conditions.

What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
