Used primarily as an anticoagulant in medical and laboratory settings, it prevents blood clotting by binding calcium ions, which are essential for the coagulation process. It is commonly employed in blood banks for the preservation of whole blood and blood components, such as red blood cells and platelets, ensuring they remain viable for transfusion. Additionally, it is utilized in diagnostic tests and research involving blood samples, maintaining their integrity during processing and analysis. Its formulation, which includes dextrose, also provides nutrients to blood cells, enhancing their survival during storage.
