Blood collection tubes are indispensable tools in medical testing and clinical laboratories. Among them, the blood collection tube containing separation gel and coagulant, namely the "SST coagulant tube", plays an important role. The blood collection tube containing separated gel and coagulant is usually marked with a specific color, usually yellow. This color design facilitates quick identification in clinical and laboratory environments, ensuring that medical and laboratory personnel can accurately select the required blood collection tubes. The yellow markings also help distinguish different types of blood collection tubes, avoiding confusion and incorrect use.

Action principle of separating gel and coagulant

1. Function of separating gel: separating gel is a substance whose density is higher than that of serum but lower than that of blood cells. This density characteristic enables it to form a physical barrier between serum and blood cells during centrifugation. When the blood collection tube is centrifuged, due to the effect of gravity, blood cells will sink to the bottom of the blood collection tube, while serum will float on top. The separation gel plays a key role in this process, ensuring that serum can be easily separated from blood cells. By forming a physical barrier, the separation of gel avoids the interference of blood cells to subsequent analysis.

2. The function of a coagulant: A coagulant is a chemical substance that can accelerate blood clotting. When blood is collected into a blood collection tube containing a coagulant, the coagulant quickly reacts with the components in the blood, initiating the process of blood clotting. The presence of coagulants causes blood to rapidly coagulate after collection, forming a stable serum sample. The standard dosage is 20-30 microliters of coagulant added per milliliter of blood.

Application of blood collection vessel containing separating gel and coagulant

1. Serum biochemical detection: serum separation gel tube is widely used in serum biochemical detection. These testing items include liver function testing, kidney function testing, electrolyte testing, etc. Various biochemical indicators in serum can reflect the physiological state and condition of the human body. The design of the serum separation tube ensures the purity of the serum sample and avoids interference from components in blood cells on the detection results.

2. Immunological testing: Pure serum samples are crucial in immunological testing. The serum samples separated from SST tubes are used for various immunological analyses, such as antibody detection and antigen detection. By detecting antibodies and antigens in serum, one can understand the immune status of the human body and diagnose whether there is infection, autoimmune diseases, etc.

Advantages of SST coagulant tube

1. Rapid sample processing: The presence of coagulants allows blood to coagulate in a short period of time, greatly reducing the time required for sample processing. This is crucial for medical testing and clinical diagnosis in emergency situations, as it can save valuable time for patients.

2. Improve work efficiency: The rapid separation of serum also enhances the laboratory's work efficiency. Experimenters can obtain pure serum samples faster for subsequent testing and analysis, reducing waiting time and improving work efficiency.

3. Ensure sample quality: The combined effect of separation gel and coagulant ensures the purity and stability of serum samples, makes the test results more accurate and reliable, and reduces errors and repeated tests caused by sample quality problems.

4. Save samples: In some cases, serum samples need to be saved for subsequent analysis. The blood collection tube containing separated gel can prevent the mixing of serum and blood cells, maintain the stability of serum samples, and facilitate the preservation.

Blood coagulant

The blood collection tube containing separated gel and coagulant, namely "SST coagulant accelerator tube", has an important use in medical laboratory and clinical laboratory. By separating gel and coagulant, this blood collection vessel can quickly separate serum, accelerate the blood coagulation process, and provide pure and stable serum samples for serum biochemical and immunological tests.
