Rapid Analysis of 25-Hydroxyvitamin D Epimers in Serum by LC-MS/MS

The C3 epimers of 25-hydroxyvitamin D have lower bioactivity than the primary metabolites and—if not chromatographically separated—can cause vitamin D levels to be overestimated. Raptor FluoroPhenyl columns provide baseline resolution of all key compounds in a fast, 5-minute analysis.
