Hydrophobic Vacuum Blood Collection Additives Serum Separating Gel

The appearance of vacuum blood collection makes blood collection easier and improves the detection efficiency. As a favorable test tube for blood collection, transportation and storage, it usually includes three parts: blood collection needle, needle holder and blood collection additive. Generally, blood collection additive will play a major role and can be applied to different biochemical, immune and other tests. According to the types of blood collection additives, they can be roughly divided into anticoagulants, coagulants and serum separating gel. Their performance will directly affect the properties and test results of blood samples. So let's focus on the introduction of blood sampling additives.

1, Coagulant accelerator

Generally, the coagulant will be evenly sprayed on the inner wall of the test tube, which can activate the fibrin and turn soluble fibrin into insoluble fibrin. At the same time, it can quickly accelerate the blood coagulation without the help of external instruments and facilities. After the blood collection with the coagulant promoting tube is completed, the pure and ideal serum can be obtained in a short time by placing it in a standing position, which is suitable for emergency biochemistry.

2, Serum separating gel

Adding separation gel in the test tube is mainly to separate serum and blood clots by its specific weight. In addition, the separation gel in the tube has good affinity with PET tube. After centrifugation, the separation gel is located between serum and blood clots, forming a barrier, which can effectively prevent them from exchanging substances, ensure the accuracy of the test results, and is applicable to serum biochemistry, electrolyte, serum immunology and other tests.

3, Anticoagulant

There are many types of anticoagulants. According to the different test items, the anticoagulants added in the anticoagulant blood collection vessel are different, which are roughly as follows:

1. Heparin sodium, heparin lithium

Heparin sodium or heparin lithium are usually added to test tubes, mainly because they have little interference with blood cells and will not affect the size of red blood cells, so they will be widely used in the determination of hematocrit and erythrocyte sedimentation rate.

2. EDTA potassium salt

EDTA will be added into the tube with two or three potassium. Because EDTA can protect the blood sample cell components, and has a great affinity for calcium in the blood, it can be complexed with it to make prothrombin unable to change, so it has an ideal anticoagulant effect. At the same time, because it will not interfere with the size of white blood cell count and can inhibit the aggregation and adhesion of platelets, it is suitable for routine hematological examination.

3. Sodium citrate

Adding a certain amount of sodium citrate into the test tube is mainly because it can complexe with calcium to form soluble calcium chelate when contacting with blood samples, which can prevent blood coagulation. It is very suitable for the examination of coagulation mechanism items, such as APTT.
