Abstract: Erythrocytes (RBCs) transfusion is a crucial treatment to save lives in case of illness or severe anemia caused by chemotherapy or blood loss due to trauma, accident or major surgery. All currently licensed additive solutions for RBCs have an acidic pH (approx. 5.6-5.8), which is far below the normal physiological pH of 7.3 of venous blood. Because blood sampling is done in an anticoagulant medium with an acidic pH, we aimed to study by flow cytometry, the morphology and physiology changes induced by acid pH. The results of our researches revealed the negative influence of the extracellular acid pH on the much earlier and faster appearance of storage lesions on red blood cells. We have demonstrated the efficiency and sensitivity of flow cytometry methods used in assessing the quality of stored components.
Keywords: RBCs, intracellular pH, storage conditions, blood banks, flow cytometry, scanning electron microscopy
