Heparin sodium, as a physicochemical substance with strong negative charge, is often added to the green blood collection vessels to prevent blood clotting and delay clotting time due to its natural anticoagulant properties. However, there are still many people who are not clear about the role it plays in the green test tube and the problems that need attention, so the following focuses will be introduced to you.
Bottled heparin sodium
Anticoagulant mechanism of heparin sodium
The anticoagulation mechanism of heparin sodium is that it can combine with antithrombin 3, which will damage the structure of antithrombin 3 and lose its activity. When it combines with coagulation factors, it will inhibit coagulation factors. When antithrombin 3 reacts with thrombin, the effect of thrombin becomes weaker, while heparin sodium will accelerate this effect. Fibrinogen cannot be converted into fibrin, and the coagulation time will naturally be prolonged.

Extraction of heparin
The key of heparin sodium is "heparin". Heparin is usually stored in the viscera and organs of mammals, and is effectively extracted from animal liver for utilization. At present, the domestic pig industry is developing rapidly. The supply of pig small intestine is sufficient and the freshness of preservation is high. Therefore, the extraction of heparin sodium in the market is mainly achieved through pig small intestine.
Precautions:
1. When it is added to the green test tube as an extracorporeal blood anticoagulant, it is necessary to select the refined and purified heparin sodium, usually of AR analytical purity, which is white powder without any impurities. Because the data of many test indexes of heparin sodium purified from crude products are not standard, it may lead to errors in the test results.
2. When heparin sodium is added into the green test tube, the powder needs to be prepared into a solution, which must be ready for use, to avoid long-term shelving, which is easy to breed bacteria, resulting in poor performance and difficult to play its role.
3. The better effect of blood anticoagulation is that 20 IU heparin sodium is used for 1 mL blood, so the dosage of heparin sodium should be controlled reasonably.
