Time Dependent Assessment of Morphological Changes: Leukodepleted Packed Red Blood Cells Stored in SAGM.

Usually packed red blood cells (pRBCs) require specific conditions in storage procedures to ensure the maximum shelf life of up to 42 days in 2-6°C. However, molecular and biochemical consequences can affect the stored blood cells; these changes are collectively labeled as storage lesions. In this study, the effect of prolonged storage was assessed through investigating morphological changes and evaluating oxidative stress.

Reference ranges of lymphocyte subsets in healthy Qatari adults.

Aim: Determine reference ranges of lymphocyte subsets in healthy Qatari adults.

Patients & Methods: Blood samples (n = 150) were investigated using four colors flow cytometery.

Results: The mean percentage and absolute values of the lymphocyte subsets were: CD3: 73.
