How to preserve blood coagulants

 

Blood coagulant is an indispensable reagent in clinical medical testing, usually used in conjunction with serum separation gel, which can facilitate the collection, extraction, and transportation of blood samples in the same test tube, simplifying relevant testing items. The main function of coagulants is to promote blood coagulation, while serum separation gel assists in extracting high-quality blood samples.

 

There are currently two common types of blood coagulants on the market: coagulant suspension and high-efficiency coagulant powder. The main components of coagulant suspension include thrombin, alcohol, silica powder, emulsifier, and surfactant. When using, it is necessary to thoroughly mix these components, apply them evenly to the inner wall of the blood collection vessel, and dry them before use.

 

To ensure the effectiveness of the coagulant suspension, it is necessary to store it in a dry and sealed environment. It is recommended to store it at a temperature of 4-8 ℃ to avoid direct exposure to sunlight. Try to use it up within the service life. The suspension is normally white, and should not be used again when there are abnormal colors, odors, or impurities.

 

The main components of high-efficiency coagulation promoting powder are high molecular polymers, coagulation factors, etc., with a white powder like appearance. When using, it is necessary to prepare a solution with water or alcohol, evenly spray it on the inner wall of the blood collection vessel, and use it after drying treatment. Dry powder can also be directly added to the blood collection vessel for use.

 

Due to the fact that high-efficiency coagulation promoting powder is a powder that is prone to moisture absorption, attention should be paid to sealing and moisture-proof during storage to prevent agglomeration of the coagulation promoting powder and to prevent impurities such as dust. Normally, high-efficiency coagulant powder that has been sealed and preserved against moisture can be effective for three years from the production date.

 

Desheng Biochemical is one of the few manufacturers in China that can produce a full range of blood collection additives. In addition to coagulant suspension and high-efficiency coagulant powder, there are also patented anti irradiation serum separation gel and various types of anticoagulants. The product range is complete and the quality is excellent, and it is highly recognized by customers!
