1. Sodium citrate is used as an anticoagulant to prevent blood clotting.
2. Fill with sodium citrate buffer solution with a concentration of 0.109mol/L (3.2%).The ratio of blood to sum is 9:1. The ratio of blood to anticoagulant is critical for valid prothrombin time results.
3. Invert the tube 5-8 times after blood collection to activate enough anticoagulant.

What is the difference between the heparin , EDTA and the sodium citrate anticoagulant？
EDTA is an inorganic anticoagulant, mainly used in hematology research, cell culture and separation and other fields. Its mechanism of action is to combine with calcium ions in the blood, so that the coagulation factors cannot be activated, so as to achieve the anticoagulant effect.
Sodium citrate is an organic anticoagulant that is also commonly used in hematology research and clinical diagnosis. Its mechanism of action is to achieve the anticoagulant effect by inhibiting the activation of coagulation factors. Heparin is a natural anticoagulant found mainly in the liver and lung tissues of animals. Its mechanism of action is to inhibit the activation of thrombin by combining with coagulation factors, so as to achieve the anticoagulant effect.
Heparin can also further enhance the anticoagulant effect by activating the anticoagulant mechanism in the body, such as activating protein c and antithrombin. EDTA and sodium citrate are chemically synthesized anticoagulants with a single mechanism of action, while heparin is a natural anticoagulant with a more complex mechanism of action and strong anticoagulant effect.
