Abstract: Transfusion medicine is an important part of the Canadian health care system. In Quebec, the Héma-Québec blood bank manages all stages from blood collection to delivery of blood products to hospitals. In recent years, the alteration of red blood cells deformability observed during storage in blood banks has returned to the forefront of discussions because of the increasing accessibility of new technologies to better characterize this property. This project objective was to develop, within Héma-Québec, a novel microfluidic approach to measure the evolution of red blood cells deformability during blood bank storage. Monitoring the deformability of six red blood cells concentrates stored at T = [2-8 °C] for 42 days determined that the performance of the microfluidic method surpassed that of a comparative method, which was also developed as part of this project. Some inconsistencies observed during the application of the microfluidic method have subsequently led to an optimization phase. Although some aspects of the method still need to be improved, the results of this project suggest that deformability could possibly serve as a quality marker of red blood cells in the same way as the most eloquent markers do.
