Effect and principle of coagulation-promoting plastic blood collection tube

The main function of the coagulant plastic blood collection tube is to make the blood coagulate quickly. This type of blood collection tube is usually used for experiments that require quick results, such as emergency tests. The blood coagulation process can be accelerated by adding some chemicals, such as coagulation factors and coagulants. Once the blood coagulates, some of the cellular and liquid components contained in it can be retained, while other components will be fixed on a specific carrier, such as a plastic polyethylene plastic tube. These carriers can be used for subsequent experimental tests such as microscopy or biochemical analysis.

The principle of procoagulant plastic blood collection tubes mainly relies on the colloidal coagulation environment formed by anticoagulants and inert polyethylene plastics. In this environment, blood can coagulate quickly, but the coagulated substances will not enter the cells, but only gather at the bottom of the test tube to form "procoagulant blood clots", which not only ensures the rapid collection, transportation and separation of samples, but also maintains the integrity of platelets to the greatest extent.
