Does the serum separation gel in the blood collection tube really adsorb sodium ions?

In recent years, with the continuous progress of medicine, it has a great impact on the efficiency of biochemical testing to a certain extent, especially clinical blood testing, because there are various additives for blood collection tubes, such as serum separation gel, heparin sodium, EDTA Potassium salts, etc., not only save time for medical staff, but also improve the accuracy of test results.

Among them, serum separation gel is the most widely used product in blood collection tubes. Its characteristic is that it can effectively prevent the exchange of substances between blood cell components and serum, and ensure the stability of blood components within a certain period of time. Recently, it has been suggested that the serum separation gel in the blood collection tube will adsorb sodium ions. Is this true? The following will give you a detailed introduction.

Usually human blood contains macro metal elements calcium, potassium, sodium, magnesium, and trace metal elements iron, zinc, copper, manganese, each of which has different effects on the human body. Therefore, after everyone collects blood, the blood is placed in a blood collection tube with serum separation gel, so that sodium ions will inevitably "coexist in the same room" with the serum separation gel.

Whether the serum separation gel will adsorb sodium ions depends on the entire separation process. The separation gel itself is composed of hydrophobic organic compounds and has thixotropy. When it is centrifuged in the same test tube with the blood that has been completely coagulated, due to the assistance of centrifugal force and the specific gravity of the separating gel, a transition phenomenon occurs, which will form layers, which are blood clots, separating gel and serum. Therefore, from the perspective of the entire separation process of serum separation gel, it will not affect the components in the blood, nor will it desorb sodium ions. Its only function is to form an isolation layer, improve efficiency, and ensure the accuracy of test results. accuracy.

In addition, there is also a situation where serum separation gel is added, and blood trapping or other undesirable phenomena occur. At this time, the performance of the separation gel needs to be considered, which has nothing to do with whether it will adsorb sodium ions.

Desheng Biochemical is a professional supplier of serum separation gels. Whether it is appearance performance, or its specific gravity, viscosity and thixotropy, there are clearly specified requirements. All parameters and indicators are determined by professionals through a lot of experiments. Therefore, long-term buyers and The number of collaborators is also increasing.
