Serum Fibroblast Growth Factor 23 Is a Useful Marker to Distinguish Vitamin D-Deficient Rickets from Hypophosphatemic Rickets

Abstract

Serum FGF23 level is the most critical biochemical marker for distinguishing DR from HR and might be a good indicator of biochemical response to the intervention. Serum FGF23 levels show utility for the diagnosis of DR and in the assessment of its response to treatment.
