Blood Collection Tube Additive-Trisodium Citrate

Vacuum blood collection tube anticoagulants, as the name says, can play a role in preventing blood coagulation. There are many types of blood anticoagulants used in modern medical examinations. The commonly used anticoagulants in medical examinations are EDTA dipotassium, EDTA tripotassium, disodium EDTA, sodium heparin, lithium heparin, potassium oxalate, and sodium fluoride. Besides, there is a small role that is trisodium citrate, also known as sodium citrate. Let's learn about sodium citrate with Desheng.

Its chemical name is sodium citrate dihydrate. is an organic compound that appears as white to colorless crystals. We know that blood coagulation pathways are divided into intrinsic and extrinsic coagulation pathways. The participation of Ca 2+ is required in the intrinsic coagulation pathway; the participation of thrombin is required in the extrinsic coagulation pathway. So we only need to get one of them to achieve the effect of anticoagulation. Sodium citrate is complexed with calcium ions in the blood to form stable calcium citrate, thereby preventing the initiation of blood coagulation mechanism and achieving the purpose of anticoagulation.

The head caps we see in the blood testing laboratory are light blue and black vacuum blood collection tubes with sodium citrate added. The blood collection tube with the light blue cap is used to detect the four items of coagulation, which is mainly combined with calcium ions in the blood sample to conduct coagulation experiments. 3.8% (equivalent to 0.109mol/L or 0.129mol/L), and the ratio of anticoagulant to blood is 1:9. The blood collection tube with the black cap is used to detect the erythrocyte sedimentation rate, that is, the erythrocyte sedimentation rate(ESR).

In addition, one of the most classic uses of sodium citrate is in blood preservation solutions for the preservation of blood in blood banks. Desheng Biochemical specializes in the production of trisodium citrate, and is also engaged in other raw materials for adding reagents to vacuum blood collection tubes, such as blood anticoagulant sodium heparin, lithium heparin, EDTA 2K, EDTA 3K, EDTA 2Na, potassium oxalate, sodium fluoride, coagulant He has developed, produced and sold high-efficiency coagulation powder, water-soluble silicifying agent and oil silicon for more than ten years, and has provided services for more than 400 blood collection tube manufacturers at home and abroad and biological laboratories. The products not only include blood collection tube additives. , as well as chemiluminescent reagents, such as luminol, acridine esters and other products.
