Quality Of Inactivated Red Cells Compared To Gamma Irradiated Red Cells

• S-303 RBCs had improved in vitro quality compared to IR RBCs with respect to potassium leakage and hemolysis post processing and throughout the storage period while containing less plasma protein. • The low plasma free hemoglobin for S-303 RBCs may result in reduced vasoconstriction due to nitric oxide binding and the low extracellular potassium may be of benefit for neonates and patients with renal failure.
