Test Overview

Test Methodology

Enzyme-Labeled Chemiluminescent Immunometric Assay

Test Usage

In combination with IGF-1 measurements, IGFBP-3 measurements are useful for the diagnosis of growth disorders, the diagnosis of adult GH-deficiency, monitoring of rhGH treatment, and as a possible adjunct to IGF-1 and GH in the diagnosis and follow-up of acromegaly and gigantism. At this time, IGFBP-3 cannot be reliably used as a prognostic marker in breast, colon, prostate or lung cancer.
