In-vitro method for determining a surreptitious use of exogenous erythropoiesis stimulating agents by a normal living subject

摘要

The present invention is an in-vitro blood assay method for determining the past and/or present use of exogenous erythropoietin by a living subject. The blood assay method detects, identifies, and determines the consequences of using an exogenous erythropoietin to generate an increase in red blood cell production in the living subject and provides a methodology by which to detect and determine both surreptitious as well as authorized therapeutic uses and applications of erythropoietin.
