[ABO/D discrepancies in the era of automation and molecular immunohematology].

ABO/D grouping errors are still causing fatalities despite the substantial decrease observed over the past thirty years. This risk reduction is due, in part, to the increased automation of immunohematology techniques, a better control of clerical errors and a better knowledge of group discrepancies. The first part of the text will summarize the etiologies of group discrepancies while the second part will expose briefly the historical and technical evolution in immunohematology.

Blood wastage reduction: a 10-year observational evaluation in a large teaching institution in France.

Context: Blood transfusion has increased significantly during the last decade and blood wastage reduction is a medical and economic challenge in hospital practice and for institutional quality, particularly in the ICU and operating theatre.

Objective: To evaluate the impact of multiple strategies in one hospital to reduce red blood cell wastage.

Design: Multicentre, prospective, comparative, observational study.

Erythrocyte-magnetized technology: an original and innovative method for blood group serology.

Background: Erythrocyte-magnetized technology (EMT) is a new fully automated method for ABO-RH-K phenotyping and antibody detection. The magnetization of red cells avoids centrifugation and washing phases. This report describes the results of an evaluation of this new technology on its specific automated system.
