Abstract

The recombinant human erythropoietins epoetin alfa (Eprex®), darbepoetin (Aranesp®) and methoxy polyethylene glycol-epoetin beta (Mircera®) were administered to greyhounds for 7, 10 and 14 days respectively. Blood and urine samples were collected and analysed for erythropoietin by ELISA, LC-MS/MS and western blotting. Limits of confirmation in plasma for western blotting and LC-MS/MS methods ranged from a low of 2.5mIU/mL, and closely matched the sensitivity of ELISA screening.
