IGF BINDING PROTEIN (IGF-BP3) BLOOD TEST
This IGF-BP3 blood test measures the level of Insulin-like Growth Factor Binding Protein 3 in the bloodstream.
IGF-BP3 is the most abundant binding protein for IGF-1 and IGF-2, playing a crucial role in regulating their availability and activity.
This test is commonly used to evaluate growth hormone function, especially in children with growth concerns or adults suspected of having growth hormone deficiency or excess. Since IGF-BP3 levels are less affected by nutritional status and daily fluctuations than other markers, it provides a more stable indicator of long-term growth hormone activity.
