The Role of Calcium in Coagulation and Anticoagulation

Abstract. The quality of the coagulation-related blood-derived products is markedly affected by the manner in which blood is collected. Standard anticoagulation solutions contain citrate which efficiently prevents blood clotting by chelation of calcium and other metal ions. However, there are two sides to the matter, which is often overlooked.
