Serum separation gel, a kind of raw material commonly used in hospital laboratory, is inseparable from many biochemical analyses. It is an inert polymer, insoluble in water, and has high temperature resistance, low temperature resistance, oxidation resistance, and high stability. Some manufacturers such as Desheng's separation glue also have the characteristics of anti-radiation.
The main purpose of serum separation gel is that it can form an isolation layer between blood cell components and serum, which can effectively prevent the exchange of substances between blood cells and serum, ensure the stability of serum components within a certain period of time, and make the test results closer to biochemical Horizontal, the separation gel tube with coagulant added can shorten the blood clotting time and quickly obtain serum. The processed blood sample can withstand the shaking and turbulence of long-distance transportation. The separation gel isolation layer can tightly adhere to the test tube after the sample is centrifuged. Above, the serum can be directly drawn by the automatic analyzer in the original state, or stored in cold storage, long-distance transportation will not affect the test results, and also avoid the influence of fibrin and hemolysis. In addition, a series of processes such as blood sample injection into blood collection tubes, serum separation, serum directly taken by the analyzer, blood sample storage, and waste disposal are all performed in the same branch, which can avoid contamination of blood samples, prevent virus infection in the blood, and ensure the inspection process Biosafety.
With the improvement of people’s health awareness, blood testing has become more common. Serum separation gel is favored by various medical institutions. There are many manufacturers of separation gel. Due to the different requirements of medical institutions for separation gel, each manufacturer produces The components of the separation rubber are different, regardless of the transparency, color, viscosity, specific gravity and other aspects of the performance. The high-quality serum separation gel can shorten the serum separation time, and the separation gel is between the serum and blood cells, which can effectively protect the serum components, so as to realize the original tube on the machine and the original tube to save the serum for future reference, reducing the possibility of errors caused by re-transfer Sex. However, the impact of inferior separation gel on the test items cannot be ignored. The use of inferior separation gel detection can increase the triglyceride (TG) in the test results abnormally. Therefore, a comparison test must be done before using serum separation gel. The following is a quick, easy and easy-to-operate method to detect triglycerides in the separation gums of various manufacturers, as follows:
- Apparatus and reagents: automatic biochemical analyzer, triglyceride (TRIG) re
