Method for removing leukocytes and thrombocytes from preserved blood and packed red cells
A method has been described for removing leukocytes and thrombocytes from preserved ACD blood and from packed red cells of the same type of blood. A system has been used comprising two connected plastic bags model "Fenval". The leukocyte and thrombocyte removal is performed by two consecutive procedures, each comprising centrifugation with subsequent fast sedimentation of erythrocytes. No filters are needed. 97.3 +/- 3.04% leukocyte removal and 96.90 +/- 5.96% thrombocyte removal as regards the preserved blood and 95.65 +/- 8.70% leukocyte removal and 98.44 +/- 0.70% thrombocyte removal as regards the packed red cells have been achieved.
