Previously, we talked about many blood collection additives, such as EDTA dipotassium, tripossium, disodium, heparin lithium, heparin sodium, sodium citrate, sodium fluoride, etc. These reagents have a common feature that can use different principles of action to prevent blood from clotting for a certain period of time, which is what we commonly refer to as blood anticoagulants. Correspondingly, it is a blood coagulant, which is an auxiliary reagent in vacuum blood collection vessels that promotes rapid blood coagulation. There are two common types of coagulants on the market: white suspensions mainly composed of thrombin, alcohol, silica powder, emulsifiers, surfactants, etc; And a white high-efficiency coagulation promoting powder mainly composed of polymer and coagulation factors. Procoagulants are usually used in combination with serum separation gels for rapid extraction of serum samples. Serum separation gel is a gel like substance used to separate serum and blood clots, while a coagulant rapidly coagulates blood and precipitates serum. Under normal circumstances, blood samples that do not contain blood coagulants will naturally coagulate, but it takes at least an hour for separated blood to coagulate. Due to the influence of external environment, the phenomenon of non coagulation or partial coagulation often occurs. In order to completely avoid this situation, the use of blood coagulants is particularly important. The application of blood coagulants greatly shortens the time of blood coagulation, improves the efficiency of obtaining high-quality serum samples, and does not affect the test results. To ensure the effectiveness of blood coagulants, special attention should be paid to the following points: when using the coagulant suspension, it is important to thoroughly mix the ingredients inside; Excessive or insufficient dosage added to the blood collection vessel can affect the effectiveness of the coagulant; After the final blood collection, it is also necessary to fully integrate the coagulant with the blood sample, so that the procoagulant effect can be better. Desheng specializes in producing coagulants, and after you purchase the product, professional technicians carefully guide you to use it correctly!
