FGF-23 Simple Plex

FGF-23 (fibroblast growth factor 23) is one of three FGF family members that appear to play a role in endocrine metabolism. It is described as being a phosphatonin, a molecule that reduces circulating plasma phosphate. FGF-23 does this, in part, by blocking Vitamin D activation. Active Vitamin D promotes intestinal phosphate absorption.
