[Annual Report 2004 - French National Reference Centre for Rare Blood Groups and Immunohaematology (CNRGS)].

In 2004, the French Reference Centre for Rare Blood Groups and Immunohaematology (CNRGS) developed 7 types of activities: 1) Studies of complex Immunohaematology issues (IH), 2) Studies of rare blood phenotypes, 3) the transfusion of patients showing complex issues, 4) IH reactive control in consistency with the 98/79/CE European Directive, 5) European studies and expertise on reactives and techniques, 6) Biotechnologies applied to blood groups, in particular RH, KEL, FY, JK, DO and CO, 7) Implementation of allo-immunization research programs (cellular immunology and grafting issues). The CNRGS efficiency is based on the 'reference-research' link thanks to the Inserm partnership and direct applications to patients allowing to a better risk management and control.
