Blood when stored at 4degC can be kept for
When blood is stored at 2-6 degC, glycolysis is reduced but does not stop. Giycosis results in the production of lactate, with a subsequent decrease in pH. Whole blood collected in CPD has a pH7.20 on day 0 and 6.84 on day 21. Preservative solutions provide the buffering capability to minimize pH changes and optimize the storage period. Ref: Medscape
