Background: It has been shown that Red Blood Cells (RBC) undergo a number of changes during liquid storage which affect their viability and their ability to deliver oxygen to the tissues. These alterations can be classified in two major groups: biomechanical and biochemical. This study wanted to analyze the effect of storage time on plasma hemoglobin, plasma glucose, potential of hydrogen (pH), and lactate levels before and after storage on the 1st, 10th, 20th, and 30th days. Method: 50 Packed red cells bags were taken for this study. From the PRC, plasma was taken on 1st, 10th, 20th, 30th days for hemoglobin plasma, glucose plasma, pH, and lactate. Data obtained were analyzed using SPSS software for windows. Result: The results showed that the level of plasma hemoglobin (Hb) and lactate increased significantly from day 1 until day 30 (P< 0.001); on the other hand, the levels of plasma glucose and pH value showed a significant decrease from day 1 to day 30 (P <0,001). Conclusion: There is a significant difference in the length of storage of the Packed Red Cells on the results of the examination of Plasma Hemoglobin levels, Plasma Glucose levels, the pH value, and Lactate levels.
