Rapid and sensitive method for erythropoietin determination in serum

Abstract

An enzyme-linked immunosorbent assay (ELISA) method for erythropoietin determination has been established by using two kinds of monoclonal antibodies with specific affinities to erythropoietin. Besides being rapid (2.5 h) and sensitive (detection limit 0.3 int. unit/L), the present method gives accurate results and is easy to perform. The method may be clinically applicable for discriminative diagnosis of polycythemia and analyses of various anemic conditions.
