CPDA-1 (Citrate Phosphate Dextrose Adenine)

CPDA-1, or Citrate Phosphate Dextrose Adenine, is a solution used in blood banking to preserve red blood cells for transfusions. It works by preventing clotting and providing nutrients to keep the cells healthy while they are stored. The citrate helps to bind calcium, which prevents blood from clotting, while phosphate and dextrose provide energy and maintain the pH balance. Adenine supports the production of ATP, the energy molecule, helping the stored blood to last longer. CPDA-1 enables safe storage and transport of blood, ensuring it remains viable for use in medical treatments when needed.
