[Quality control of reactant lots at the Nation Blood Group Reference Center (CNRGS). Data for the year 1998].

The reagents used for blood group analyses are subject in France to the same regulations as other reagents. A file must be submitted for each reagent to the Agence française de sécurité sanitaire des produits de santé. Furthermore, each production lot must be checked by the Centre national de référence pour les groupes sanguins (CNRGS) for control before marketing. These controls allow a comparative quality assessment of the reagents. The investigation by the CNRGS of the problems encountered in the every day use of these products makes this quality control even more accurate.
