"Traces of Dynepo, a biosimilar EPO, were found in Rasmussen's urine," AFLD president Pierre Bordry said. "Rasmussen's test could not be declared positive because of the positivity criteria of the World Anti-Doping Agency."
An EPO test is deemed to be positive is the erythropoietin is obtained chemically but due to the fact Dynepo is made from human cells WADA fear that is could be mistaken with human EPO resulting in the "non-positive" result.
