The Insulin-like Growth Factor-binding Protein 3 (IGFBP-3) Test measures the level of IGFBP-3 in the blood. The levels for this protein are closely related to the body's production of Human Growth Hormone (hGH). Abnormal levels of IGFBP-3 can be indicative of pituitary gland disorders and abnormalities in growth hormone production. IGFBP-3 can provide a more accurate determination of growth hormone levels than IGF-1 in children.
Turnaround time for this test is typically 1-2 business days.
The Insulin-like Growth Factor-binding Protein 3 (IGFBP-3) Test has no special requirements.
