Special Serum Separating Gel For Blood Sample Collection

What is the special serum separating gel for vacuum blood collection tube? Many people do not understand this. In fact, when we do blood testing in the hospital, it is difficult to detect the transparent colloid at the bottom of the blood collection vessel without careful observation. The serum separating gel developed and produced by Desheng is a hydrophobic material, composed of high molecular polymers, with good thixotropy and stability, which is suitable for long-term storage and transportation of blood.

Mechanism and principle of special serum separating gel for vacuum blood collection

Once the serum separating gel and coagulated blood are centrifuged, the separating gel is affected by centrifugal force, and the hydrogen bond network structure is destroyed into a strip structure, and the separating gel becomes a substance with low viscosity. The blood component contains serum and blood clot. The blood clot is heavier than the serum, and the proportion of the separating gel is between the serum and the blood clot. The blood clot heavier than the separating gel will move to the bottom of the blood collection vessel, forming three layers of serum, separating gel and blood clot in the tube.

Take out the blood collection tube from the centrifuge, the separating gel loses centrifugal force, and the hydrogen bond structure is combined again to restore the gel state with strong initial viscosity, separate the serum and blood clots, prevent their interaction, ensure the original character of blood sample collection within a certain period of time, and promote more accurate detection results.

Parameters of serum separating gel:

In addition, there should be enough adhesion between the separating gel and the tube wall in the vacuum blood collection tube, and the adhesion is closely related to the material of the blood collection tube. The blood collection tube is divided into glass tube and plastic tube. The glass tube is mainly composed of silicate with hydrophilic material. After blood collection, there may be attached water molecules on the inner wall of the tube. Therefore, the separating gel cannot directly adhere to the inner wall of the tube.

Sometimes after a period of placing, Ka or enzyme substances in red blood cells will gradually spread to the serum through water molecules, so the glass blood collection vessel can store the serum for about 3 days in its original state. The plastic blood collection tube is made of hydrophobic material, the tube wall will not have any water molecules, the separation glue will adhere firmly, and the potassium in the red blood cells will not spread to the serum, so the cold storage time can reach one week.
