IGF-BP3 (Insulin-like Growth Factor-binding Protein 3) LabCorp
This test measures IGF-BP3 in the blood for insight into Human Growth hormone (hGH) levels.
What is this test?
Insulin-Like Growth Factor Binding Protein 3 (IGF-BP3) is the major transporter of Insulin-Like Growth Factor-1 (IGF-1), and it also helps regulate and lengthen the life of IGF-1. Measuring IGF-BP3 levels can provide insight into the amount of hGH in the blood.
Human Growth Hormone is responsible for growth and development during childhood and adolescence, and it also plays an important function in wound healing, recovery, body composition, and more. hGH levels decline naturally as we age, and integrative therapies are available to help replenish hGH levels (as appropriate for the patient). hGH can also decline as a result of certain medical conditions, lifestyle factors, and others. IGF-1 and IGF-BP3 are closely related to the release of hGH.
Who is this test for?
The IGF-BP3 Test can provide a more complete picture of hGH production in the body. If you are considering Peptide Therapy, this test can illuminate whether your hGH levels are depleted. This lab is typically ordered alongside the IGF-1 Test.
