Problems to be paid attention to in clinical application of separation gel blood collection tube

Separating gel blood vessels have been widely used in clinical laboratories. Separating glue can form an isolation layer between cell components and serum (plasma), effectively prevent the exchange of substances between blood cells and serum (plasma), and ensure the stability of serum (plasma) components within a certain period of time.

There are generally two types of separation gel blood collection tubes commonly used in laboratories: serum separation gel coagulation tube and plasma separation gel anticoagulation tube. The serum separation gel coagulation tube is to add a coagulant to the blood collection tube to shorten the blood coagulation time, quickly get the serum, and report the result in the shortest time. The glass blood collection tube does not need to add coagulant, the blood contacting the glass tube wall will trigger coagulation. When xr and xn blood coagulation factors come into contact with plastic blood collection tubes, they are very weakly stimulated, and coagulants need to be added to shorten the clotting time. The plasma separator gel anticoagulant tube is sprayed with anticoagulant such as lithium heparin on the inner wall of the separator gel blood collection tube to meet the needs of rapid plasma biochemical emergency testing.

Separation gel is a thixotropic mucus colloid composed of hydrophobic organic compounds and silica powder. The structure contains a large number of hydrogen bonds. The existence of hydrogen bonds constitutes the chemical basis of separation gel thixotropy. Separation gel quality The specific gravity of separation gel is between serum (plasma) and blood cells, which is the physical basis for the reversibility of separation gel and the separation of serum (plasma). If the quality of the separation gel for blood collection tubes is poor, and the specific gravity cannot meet the requirements, it will inevitably affect the separation of serum (plasma), and the separation gel and serum (plasma) are likely to be intertwined.

Although the components of the separation gel are inert to the blood, there is no guarantee that it will have no effect on all manufacturers' detection systems and all items. There are many manufacturers of blood collection tubes, and each company has different components and ratios of the separation gel, and unique materials are mixed to maintain its stability. Therefore, the transparency, color and performance of the separation glue of each company are different.

Desheng is a long-established manufacturer of serum separator gels and has more than ten years of R&D and production experience. The separation glue produced by Desheng is mainly acrylic system and resin system. Three types of separation glues: transparent, translucent and opaque can be customized according to customer needs. The conventional packaging is 20kg/barrel and 25kg/barrel, and there are plastic barrels and iron barrels. , Other packaging can also be customized according to customer needs.
