We represent an organization of transfusionnel advice at a regional level and we develop arguments and stages having allowed us to lead to this choice. This target was reached in two stages, which took place over 3 years. The regional transfusionnel advice leans on three fundamental points: a planned permanent organization, skilled and formed actors as well as adapted tools. Tending to a homogeneous organization between every blood bank center seems to be coherent towards the current configuration of blood donation in France.
