title: Quality determinants of erythrocyte destined for transfusion.
abstract: An overview is given of a series of standard assays to evaluate the quality of red cell concentrates for transfusion. These are visual inspection, assessment of hemolysis, quantitation of 2,3-DPG and nucleotide levels (especially ATP) and evaluation of morphology. These parameters, relatively easy to measure, are main determinants of in vivo recovery after transfusion. In addition, some other assays are described, which should give more information about the function of red blood cells after transfusion. These assays include plasma-induced hemolysis, binding of annexin-V, deformability measurements and a rat model to judge oxygen delivery by human red blood cells (RBC). Especially in judging new protocols for the preparation of red cell products, involving e.g. improved additive solutions or pathogen inactivation methods, these quality parameters should not be compromised.
