ABSTRACT
A rare blood group is usually defined as the absence of a high prevalence antigen or the absence of several antigens within a single blood group system, if its prevalence in France is 4/1000 or less in the general population. An individual with a rare blood phenotype can develop a naturally-occurring or immune antibody corresponding to his rare specificity. In case an extremely low stock of compatible blood is available at the national level, a so-called "transfusion deadlock" is described. Most of the individuals with a rare blood group are coincidently identified when a routine pretransfusion testing or pregnancy follow-up is performed, if the antibody(ies) corresponding to the rare specificity is(are) present. Other individuals are discovered following a systematic red cell typing, or family investigations in siblings. One hundred and twenty-one rare blood specificities and 42 rare blood genotypes are currently defined at the French National Reference Laboratory for Blood Groups (CNRGS-Paris). The French national registry of individuals with a rare blood phenotype/genotype includes about 9600 people, who are urged to regularly donate blood for the National Rare Blood Bank. This bank, based on a homologous blood transfusion program, is in charge of the long-term storage of rare frozen blood units, that can only be delivered after receiving authorization from the CNRGS. The global and individual care management of the individuals with a rare blood group, concerning potentially several hundred thousand people in France, requires a close cooperation between all the protagonists within the transfusion chain.
