STUDY OF BLOOD STORAGE EFFECTS ON NEUTROPHILS TOTAL COUNT, PHAGOCYTIC ACTIVITY AND MORPHOLOGY

Transfusion of stored blood faces many problems, and Neutrophils retardation is one of these. A total of ten human blood samples were collected and used upon this study to investigate storage effects on Neutrophils total count, phagocytic activity and morphology. The results showed deterioration in these parameters after two days; 48 hours of storing, due to apoptosis induction. Conclusion: Upon storing whole blood at 4°C, apoptosis, total count and phagocytic activity retardation can be steady up to 24 hours, without adding any materials for preservation or cytokines, otherwise retardation of these parameters will be significant after 36 hours.
