CPDA is widely used in medical and clinical settings as an anticoagulant and preservative solution for blood storage. It is primarily employed in blood banks to extend the shelf life of donated whole blood and red blood cells, ensuring their viability for up to 35 days. The solution helps maintain the functionality of red blood cells by providing essential nutrients and preventing clotting. This makes it critical for transfusions, surgeries, and emergency medical treatments where a reliable supply of blood is essential. Additionally, CPDA is utilized in research laboratories for studies involving blood preservation and hematology. Its effectiveness in stabilizing blood components makes it a key tool in both healthcare and scientific applications.
