[Clinical selection of blood donors].

For 20 years, the organization set up to insure the blood transfusion safety has never stopped strengthening. It is based on clinical and epidemiological selection of the blood donation candidates, biologic selection of blood donations and different physico-chemical techniques for pathogens reduction or inactivation in blood products. In France, this organization is optimized by the assertion of the voluntary and non-remunerated character of blood donation registered in the law of January 4th, 1993. The blood donors selection is structured in three successive stages. The first stage is the pre-donation information. The second stage begins with reading and filling out an info-questionnaire which prepare for an interview with a physician. This interview is specially directed to prevention of transfusion-transmitted infections and the prevention of adverse reactions after a 400 to 600 mL collection of whole blood or components. Finally, the third stage is the delivery of a post-donation information which invites the donor to contact the "établissement français du sang" (EFS) in case of a new event arisen after the donation or in case of reviewing of its own answers during the medical interview.
