Product Description

With the comprehensive development of medical technology, blood collection tube reagents also play an important role, such as serum separation gel, heparin sodium, heparin lithium, EDTA potassium salt, etc., which are all common reagents in blood collection tubes. Among them, the application of serum separation gel is more common. It can be used in combination with coagulants to quickly obtain serum in a short time and report the results, which greatly improves the convenience for medical staff.
Due to the wide application of separating gel, the market share has increased, and the number of manufacturers has also increased. However, in practical applications, there are many cases where the separating gel does not work well. Flip, flow phenomenon. So why do these phenomena occur? What exactly is the reason for the poor separation?
1. The quality of the separating gel
The specific gravity of the separating gel is often between serum and blood clot, 1.045-1.065g/cm3, which is a key indicator of whether the separating gel is turned over, and it is also a basic indicator. If the quality of the separating gel is poor and the conventional specific gravity index requirements are not met, this will definitely affect the inversion effect, resulting in the mixing of the separating gel and serum, which will interfere with the detection.
1. Incomplete coagulation of blood
Sometimes it is found that the serum separation gel will not separate the blood clot and serum after centrifugation. This is because the blood is not completely coagulated before the centrifugation on the machine, which will cause fibrin to be mixed in the isolation layer. Therefore, we must pay attention to the time to wait for the blood to completely coagulate. Generally, the serum separation gel test tube with a coagulant is added. After the blood sample is drawn, the waiting time for coagulation is about 30 minutes.
3. Centrifugation room temperature conditions
Whether the separation of serum is effective is closely related to the temperature conditions of the centrifugation gel. In normal centrifugation at room temperature, although the serum is clear, oil beads of different sizes still appear in a few samples. However, when centrifuged at low temperature, no oil beads are found in the serum. . In addition, if the daily storage temperature exceeds the temperature of the separation rubber tube, the phenomenon of fusion of the separation glue and blood will occur, which may cause errors in the test results.
Nowadays, there are many manufacturers producing serum separation gel, and each manufacturer has different production processes, added components and proportions of the separation gel, so the performance of serum separation gel is also different. Since its establishment in 2005, Desheng Biochemical has been committed to the research and development and production of serum separation gels. It not only has rich experience, but also has been innovating in technology. The key indicators of serum separation gels, such as specific gravity, physiological inertness, stability and Anti-radiation functions, etc., are strictly accurate to prevent overturning and other problems.
