Is there Anticoagulant in the blood coagulation test tube?

 

Hemagglutination test is actually a coagulation test in clinical practice, which is generally a required examination before surgery to understand whether the patient is at risk of bleeding. The inspection method is to use a specific test tube to collect blood samples, process them with reagents in the test tube, and then perform machine testing to obtain results. As a necessary reagent in clinical test tubes, does Anticoagulant also exist in blood coagulation test tubes? Let's have a detailed chat with everyone below.

 

1、 Hemagglutination test tube

The hemagglutination test tube is generally made of glass, with transparency and corrosion resistance. The inner wall is usually coated with a layer of silicide to avoid blood wall hanging. At the same time, an appropriate amount of Anticoagulant is added to the tube. From this point of view, there are Anticoagulant in the hemagglutination test. However, due to the variety of Anticoagulant and the different colors of test tubes, special attention must be paid to which Anticoagulant is added to the hemagglutination tube.

 

2、 Type of Anticoagulant

Anticoagulant commonly used clinically include EDTA dipotassium, heparin sodium/heparin lithium, sodium citrate, etc. These Anticoagulant have different mechanisms of action, but they inhibit the blood coagulation process by combining with calcium ion and magnesium ion plasma in the blood. The Anticoagulant in the blood coagulation test tube is sodium citrate. Because its reaction process is completed by using citrate, it can effectively and quickly prevent blood coagulation, and is suitable for coagulation test.

 

3、 Sodium citrate usage in blood coagulation experiments

When using Anticoagulant sodium citrate, pay attention to whether its concentration and dosage meet the requirements. If too much Anticoagulant is added, the reaction time may be prolonged or the results may be inaccurate. The correct concentration is 3.2% or 3.8%, that is, 0.109mol/L or 0.129mol/L, and the ratio to the blood sample is 1:9.

 

In blood coagulation experiments, an appropriate amount of sodium citrate is usually added to the test tube to prevent blood coagulation and help improve the efficiency of the blood coagulation experiment. However, the premise is that the performance of sodium citrate is stable and the experimental personnel operate properly. As a raw material manufacturer of blood collection vessel additives, Desheng has its own research and development team and production line. No matter it is serum gel or Anticoagulant, it basically has no adverse problems during use, and has a high turnover rate. It is a supplier that everyone is keen to choose and trust.
