Blood Collection Tube Additive |
Blood sampling additives have functions such as preventing blood coagulation, protecting blood components, and promoting blood component separation. The use of these additives can ensure the quality and stability of blood samples, thereby improving the accuracy and reliability of laboratory testing results. They play an important role in medical laboratories as they can meet different experimental needs.
Additives for blood collection vessels
1, The addition of anticoagulants has multiple effects on blood testing
Firstly, anticoagulants can prevent blood clotting, thereby maintaining the liquid state of the blood sample and facilitating laboratory testing and analysis. For example, in blood routine testing, the addition of ethylene diamine tetraacetic acid anticoagulant can keep red blood cells, white blood cells, and platelets in a dispersed state, enabling accurate counting and classification of these cells.
However, it should be noted that different anticoagulants have different effects on blood testing. For example, in addition to preventing blood clotting, heparin anticoagulants may also have an impact on the detection results of some coagulation indicators. Therefore, when selecting anticoagulants, it is necessary to choose the appropriate type and concentration of anticoagulants based on specific testing items and requirements.
In addition, the addition of anticoagulants may also have an impact on certain testing items. For example, in certain biochemical tests, the addition of anticoagulants may interfere with enzymatic reactions or affect the determination results of certain chemicals. Therefore, in this case, special treatment of blood samples or the use of other types of anticoagulants may be necessary.
2, Protecting blood components
After collecting blood samples, they need to be processed and analyzed, which usually takes a certain amount of time. During this process, some components in the blood may undergo changes, such as a decrease in blood sugar and enzyme inactivation. To solve this problem, some stabilizers are often added to the blood collection vessels. The function of stabilizers is to protect the components in the blood and keep them stable for a certain period of time. For example, fluoride is a commonly used stabilizer that can inhibit the degradation of glucose, thereby maintaining stable blood sugar levels. Another commonly used stabilizer is oxalate, which can inhibit the activity of certain enzymes and maintain the stability of blood components. By adding stabilizers, it can be ensured that the components in blood samples remain stable during processing and analysis, thereby improving the accuracy of detection results.
3, Promote the separation of blood components
In blood testing, it is often necessary to analyze different components in the blood. In order to facilitate this analysis, serum separation gel is sometimes added to the blood collection vessel. The function of separation gel is to promote the separation of different components in the blood. During the centrifugation process, the separation gel can separate different components in the blood, forming a clear interface. This can make it more convenient to detect and analyze specific components. For example, in serological testing, separation gel can separate serum and red blood cells, making it easier to detect the components in serum. By adding separation adhesive, the experimental operation steps can be simplified, and the detection efficiency and accuracy can be improved.

4, The effect of adding coagulants on blood testing
Blood coagulants can shorten the time required for blood coagulation, thereby improving clinical work efficiency. Of course, if the quality of blood coagulants is poor, it may lead to too long or too short coagulation time, affecting the accuracy of test results.
Blood coagulants do not pose any harm to the human body as they are only used outside the body to detect disease and do not enter the body. However, when using blood coagulants, attention should be paid to their quality to ensure the accuracy of the test results.
The specific use of different blood collection tube additives
| Types of additives for blood collection vessels | Mechanism | Package |
| Coagulation promoting tube | In the accelerator tube, spray will be used to make the accelerator attach to the inner wall evenly, so that the blood can be quickly and fully mixed after blood collection, and the clotting time can be shortened | Suitable for emergency biochemistry |
| HEPARIN TUBE | Heparin sodium or heparin lithium is an excellent anticoagulant that has little interference with blood cells, does not affect the size of red blood cells, and does not cause hemolysis | Suitable for hematocrit and general biochemical measurements |
| Blood routine tube | EDTA can chelate with calcium ions in the blood, thereby playing an anticoagulant role without affecting white blood cell count and size, while also inhibiting platelet aggregation | Suitable for routine hematological examinations |
| Blood coagulation tube | An appropriate amount of sodium citrate anticoagulant is added to the tube, as citrate can bind with calcium to form a soluble calcium chelate, which can promote blood coagulation | Suitable for examination of coagulation mechanism items, such as APTT |
| Blood glucose tube | The addition of sodium fluoride as an inhibitor in blood collection vessels, as well as the special treatment of the inner wall of the test tube, can ensure the original characteristics of the blood sample for a certain period of time, while the metabolism of blood cells is stagnant | Suitable for blood glucose testing and glucose tolerance testing |
Blood sampling additives play an important role in preventing blood coagulation, protecting blood components, and promoting blood component separation. The use of these additives can ensure the quality and stability of blood samples, thereby improving the accuracy and reliability of laboratory testing results.
