Recherche des anticorps antiérythrocytaires : analyse d'erreurs au Contrôle national de qualité

The French quality control is organized by the French Health Products Safety Agency. In 2005, the immuno-hæmatology testing control included the screening of an anti KEL 1 antibody. 17 out of 2639 laboratories (0,64%) answered 'negative screening'. All laboratories received a questionnaire in order to understand the failure. In this paper the authors present the detailed laboratories' responses and failure explanations.
