Precautions for storage and use of blood sampling additives

Do you know why a cap is used when collecting blood vessels? It's a colorful collection of blood vessels? This is because different colored caps are needed to distinguish different test tubes, and different additives are added to different test tubes, resulting in different testing items. Some of the blood collection vessels can clearly see a thick layer of colloidal substance, which is serum separation gel, used to extract serum or plasma samples. The original property of serum separation gel is a fluid substance with high viscosity, so its presence in the blood collection vessel is relatively strong.

There are coagulants or anticoagulants used in combination with serum separation gel, and anticoagulants can also be used separately. Accelerator can be divided into two forms: accelerator suspension and high-efficiency accelerator powder; Anticoagulants include heparin sodium, heparin lithium, dipotassium ethylenediaminetetraacetate, tripotassium ethylenediaminetetraacetate, disodium ethylenediaminetetraacetate, sodium fluoride, potassium oxalate, and trisodium citrate, all in powder form. These additives need to be formulated into a solvent that is evenly sprayed on the inner wall of the blood collection vessel, and then dried. At this time, a thin layer of misty substance can be seen on the blood collection vessel. There is also an additive that is used in every blood collection vessel, namely silicifying agent, which is a substance that appears to have a low presence but plays a very important role.

Additives for blood collection

These additives have different functions and original properties, so the following points should be noted during storage and use:

1. Serum separation gel: As serum separation gel is a highly viscous adhesive substance, it is necessary to take protective measures when using it to avoid contact with the skin or clothing, which is difficult to clean. When storing, it is necessary to avoid direct sunlight and store it indoors in a dry and cool place.

2. Accelerator: When storing the accelerator suspension, attention should be paid to sealing and avoiding light. A temperature of 4-8 ℃ is more suitable. When using, shake the accelerator suspension to evenly distribute the active ingredients inside; Efficient coagulation promoting powder needs to be stored in a dry environment, and when used, a solution should be prepared with a certain proportion of water or alcohol according to the requirements.

3. Anticoagulants: The original properties of blood anticoagulants are mostly colored powder, and they need to be sealed and moisture-proof when stored to prevent moisture absorption and agglomeration. It is not recommended to store anticoagulants in solution for a long time, as they have better effects when used immediately.

4. Silicification agents: Silicification agents are divided into two types: water-soluble silicification agents and silicone oil. Water-soluble silicification agents need to be diluted with deionized water and sprayed on the inner wall of the blood collection vessel; Silicone oil, on the other hand, needs to be diluted with light petroleum and evenly sprayed into the blood collection vessel. At this time, it is necessary to wait for the blood collection vessel to dry and the light petroleum to completely evaporate before adding other reagents.
