NCT03889834

Brief Summary

The purpose of this study is to evaluate if differences between samples of subjects obtained before autologous blood transfusion or samples of non-transfused subjects and samples of subjects after autologous blood transfusion can be identified. Analyses performed will focus on the morphological and biochemical parameters of red blood cells and associated microparticles. The final goal would be to find markers of autologous blood transfusion, that could be used to identify such doping practice.

Eligibility Criteria

Age18 Years - 35 Years
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:
