[Biobanks and blood transfusion in France: a tool for public health]

Abstract

Donor and recipient sample biobanks are a precious tool in hemovigilance studies as well as in epidemiological and biological research, in particular with regards to safety against blood-borne agents. This paper describes the main transfusion biobanks existing in France and gives their advantages and limits. The National blood donation biobank, organized for medicolegal reasons, preserves samples of each blood donation for a 5-year period. The biobank of the Blood and Organ Transmissible Infectious Agents (BOTIA) project stocks paired donor-recipient samples with a research objective. Preserved over a long period of time, such transfusion biobanks will be useful in terms of public health, as a reflection of the biological state of a population at a given moment.
