In the medical field, blood testing is an important means of diagnosing diseases, monitoring conditions, and evaluating treatment outcomes. In order to obtain accurate blood detection results, the quality of blood samples is the key. As a special tubular container for blood collection and separation of serum and blood cells, the separation gel tube is widely used in clinical, laboratory and medical fields, and plays an important role in ensuring the quality of blood samples. Next, we will introduce the separation gel tube for blood collection in detail.
Serum separation gel
Operating principle of separation gel tube
The separating gel tube is usually composed of collecting tube, gel and anticoagulant, and its working principle is based on the functional design of different parts:
1. Collecting tube: the external part of the separating gel tube is a tubular structure that collects blood, and the blood samples of patients are collected into the tube using standard blood vessel collection methods.
2. Separation of gel: the colloidal layer is the core part of the separation of gel tube. Gel is usually composed of resin glue or acrylic acid and other materials. Its density is higher than that of blood cells in the blood, but lower than that of serum. During centrifugation, the blood sample is divided into two parts: the blood cells are deposited to the bottom of the tube during centrifugation, and the serum is suspended above the separated gel.
3. Anticoagulant: the anticoagulant in the separation gel tube can prevent blood coagulation and maintain the effect of serum separation. Common anticoagulants include EDTA dipotassium, heparin lithium/heparin sodium, etc.
Characteristics of separation gel tube
1. Excellent chemical stability: the separation gel tube should have good corrosion resistance, be able to withstand the effects of a variety of chemicals, ensure that no harmful substances will be produced due to chemical reactions during use, so as to ensure the safety of blood samples.
2. Biocompatibility: the separation gel tube has good compatibility with human blood tissue, reducing possible adverse reactions during use.
3. Physical properties: the separating gel tube has sufficient mechanical strength and toughness to withstand the pressure and friction during the collection process, while maintaining good sealing performance to prevent blood leakage.
4. Ease of use: The design of the separation gel tube is simple and easy to use, which is convenient for medical staff to collect and process blood and reduces the complexity of sample processing.
5. Diversified specifications: The separation gel tube has various specifications, which can meet the needs of different laboratories and medical places, and ensure the comprehensiveness and flexibility of sample collection.
Application of separating gel tube in blood collection
1. Sample collection: When collecting blood samples, the medical staff will use the separated gel tube as the blood collection tube. They will needle the blood collection into the patient's blood vessels and introduce the blood into the tube. In this process, due to the special design of the separation gel tube, different components in the blood began to be initially stratified.
2. Sample processing: After blood samples are collected, the medical staff will place the separation gel tube in a suitable position to stand for a period of time. After standing, put the tube into the centrifuge for operation. After setting the time and speed, under the action of separating gel, the red blood cells and plasma in the blood will be naturally stratified according to the specific gravity difference.
3. Sample extraction: After blood stratification is completed, medical staff can easily extract the upper layer of serum. Due to the complete separation of serum and blood cells, the extracted serum has a high purity and will not contain impurities or blood cell components.
4. Sample transportation and storage: After extracting the serum, medical staff store it in an appropriate container and transport and store it according to relevant regulations. During this process, the completely stratified serum can maintain a relatively stable state without turbidity or deterioration, providing high-quality samples for subsequent detection and analysis.
5. Clinical application: The separated gel tube is widely used in clinic, and doctors can diagnose, monitor and evaluate the patients' condition according to the test results. For example, by detecting biochemical indicators in serum, doctors can understand the patient's liver and kidney function, blood sugar and lipid levels, etc; By detecting viral antibodies in serum, doctors can diagnose whether a patient is infected with a certain viral disease.
As an important blood collection and separation tool, separation gel tube plays an irreplaceable role in medical, clinical and scientific research fields.
