Which additives are used for blood gas analysis

 

In the hospital, different test items have different requirements for blood collection, which may be whole blood test, serum test or plasma test, which requires vacuum test tubes with different additives. Among these experimental items, there is one item that attracts people's attention, that is, blood gas analysis. What kind of additive test tube does it use? Here's a detailed introduction.

 

In fact, the test tube containing heparin is used for blood gas analysis. Heparin is a natural anticoagulant, which was originally stored in animal liver organs and extracted. Later, it was found that the pig intestine also contains heparin. In addition, the domestic pig industry is developed and the supply is sufficient, so the current heparin preparations are basically from pig intestine.

 

Why do we need to use heparin tube instead of vacuum tube with other additives? This is still inseparable from its efficacy. It can disrupt the coagulation process and control the effect of coagulation factors from the source, so it can achieve the purpose of preventing blood coagulation. Both heparin sodium and heparin lithium are extracorporeal anticoagulants commonly used in experiments, and are also the only anticoagulants used for blood gas analysis samples.

 

For blood gas analysis substances, it is required to ensure that the concentration of heparin sodium or heparin lithium is lower than 200IU/mL of blood, and the concentration of blood dilution does not exceed 5%, otherwise it is easy to lead to inaccurate detection. In addition, there is another problem related to blood gas analysis, that is, insufficient anticoagulation or small blood clots may occur, which may block the blood gas analyzer and lead to invalid test results. Pay attention to the anticoagulation time and the quality of heparin sodium.
