Erythrocytes stored in CPD SAG-mannitol: evaluation of their deformability.

The erythrocytes deformability of three blood samples coming from healthy donors has been evaluated by Laser-assisted Optical Rotational Cell Analyzer (LORCA). Blood samples were stored in CPD SAG-mannitol. The study of progressive reduction in the Elongation Index (EI) during the preservation may be used as way of evaluation of erythrocyte vitality in stored blood samples.
