What are the biochemical blood collection tubes?

Biochemical blood collection tubes are divided into no-additive tubes (red cap), coagulation tubes(orange-red cap), and separation rubber tubes (yellow cap). The inner wall of the high-quality no additive blood collection tube is evenly coated with inner wall treatment agent and tube mouth treatment agent to avoid cell breakage during centrifugation and affect the test results, and the inner wall of the tube and serum are clear and transparent, and there is no blood hanging on the tube mouth.
In addition to the inner wall of the coagulation tube being uniformly coated with the inner wall treatment agent and the nozzle treatment agent, the spray method is adopted in the tube to make the coagulation accelerator evenly attached to the tube wall, which is convenient for quickly and fully mixing the blood sample after sampling, which can greatly shorten the coagulation time. And there is no precipitation of fibrin filaments to avoid blocking the pinhole of the equipment during sampling. When the separation rubber tube is centrifuged, the separation gel is moved to the center of the tube, which is between the serum or plasma and the blood formed components. After the centrifugation is completed, it solidifies to form a barrier, which completely separates the serum or plasma from the cells and ensures the stability of the serum chemical composition. , no significant change was observed under refrigeration for 48 hours.
Heparin is added to the inert separation rubber tube, which can achieve the purpose of rapid separation of plasma, and the sample can be stored for a long time. The separation hoses described above can be used for rapid biochemical assays. Separation gel heparin tubes are suitable for biochemical testing in emergency, acute intensive care unit (ICU), etc. Compared with the serum tube, the biggest advantage is that the serum (plasma) can be separated quickly, and the second is that the chemical composition of the serum (plasma) can be stable for a long time, which is convenient for transportation.
