# Insulin-like Growth Factor-binding Protein 3 (IGFBP-3)

> This test measures the level of a protein that carries and controls insulin-like growth factor-1 (IGF-1), a substance vital for tissue growth and development. Because your body makes this protein in response to growth hormone, the test helps show whether your pituitary gland is functioning correctly.
