Background: Fibroblast growth factor 23 (FGF23) is a key protein in bone homeostasis regulatingserumphosphateand calcitriol (1,25(OH)2D3) concentrations. Analytical performance and reference ranges of FGF23 assays differ by molecule assayed (intact or C-terminal FGF23) and manufacturer. We aim to establish reference interval values for both cFGF23 and iFGF23 in a paediatric population.Methods: Writt...
