Groupes sanguins et recherche des anticorps anti-érythrocytaires : analyse d'erreurs au Contrôle national de qualité en 2006

Further to a survey set up in 2006 over 2600 laboratories by the French Agency for Health Product Safety (AFSSAPS), seven ABO grouping errors and 53 negative answers to RBC antibody screening with a serum containing anti-RH1 antibody, have been found. A questionnaire sent to the involved laboratories revealed non-analytical errors already met in previous cases. Besides, the analytical stage has also induced RBC antibody screening errors due to a wrong serum collection by the automat. Here are displayed the analysis of the questionnaire results and proposed corrections.
