Serum sTfR Levels May Indicate Charge Profiling of Urinary r-hEPO in Doping Control

Abstract

A significant correlation was found between the relative amount of basic u-hEPO variants and the relative levels of sTfR, demonstrating that the relative levels of sTfR may be used as a marker to select urinary samples for further analysis of r-hEPO by IEF in routine doping control.
