GFBP-3 Blood Test (IGF Binding Protein 3)
The key to your growth hormone and bone health.
The IGFBP-3 Blood Test measures the level of insulin-like growth factor binding protein 3 (IGFBP-3) in the blood. IGFBP-3 is the main carrier protein for insulin-like growth factor 1 (IGF-1), a hormone that promotes growth and helps maintain bone and muscle. Because IGFBP-3 reflects growth hormone activity, this test is used to assess growth hormone status, investigate suspected growth hormone deficiency or excess, and support the monitoring of bone health and related endocrine conditions. It is suitable for adults and children being investigated for growth disorders, pituitary dysfunction, or unexplained changes in bone density.

Why it matters
IGFBP-3 is a stable and reliable marker of growth hormone action. Measuring it helps clinicians evaluate pituitary function, investigate growth abnormalities, and assess conditions that affect bone turnover and skeletal health. Early identification of abnormal IGFBP-3 levels can guide further testing and treatment, supporting better long-term bone and endocrine outcomes.
