The use method and precautions of coagulant

Product Description

Coagulant is a common additive for blood collection tubes. It is also called a suspending agent. It can be made into vacuum blood collection tubes and injection blood collection tubes. It has the function of quickly promoting blood coagulation and is commonly used in clinical biochemical testing. Blood coagulant is composed of thrombin, alcohol, silica powder, emulsifier, surfactant and so on. Its appearance is a white suspended liquid with a faint smell of organic solvents, which is non-toxic and harmless.



How to use coagulant:

Machine spraying or manual adding method can be used. During the adding process, keep stirring to keep the suspension uniform. You can use the machine to stir. After stirring and adding, it can be used after *****0℃ hot air drying. ****0ul of coagulant It can quickly coagulate **5ml of blood at ****5°C.

 

Precautions for the use of coagulant:

1. When the blood sampling environment temperature is lower than *0℃, in addition to appropriately increasing the amount of coagulant added, it is necessary to increase the number of inversions and mixing to prolong the clotting time. If rapid detection is required, it is better to use a water bath at *6℃. .

 

2. Insufficient coagulation will cause blood cells and fibrin filaments to hang up and mild hemolysis, which may stop the coagulation process, or there may be no serum separation after centrifugation.

 

3. After blood collection, if the blood and the coagulant are not fully fused and centrifuged, it is easy to form fibrin jelly-like coagulation or fibrin filaments whose specific gravity is smaller than that of blood clots, so they stay in the serum layer and partially adhere to the separation gel. , If you directly go on the machine at this time, it can cause the automatic analysis blood sampling needle to block.

 

4. After opening the coagulant, it needs to be sealed and stored, below 4℃, and used up within 7 days.

 

5. It is forbidden to use it when it is found that there are impurities and foreign bodies in the coagulant with abnormal odor, abnormal color, and the expiration date.

 

6. The coagulant is an organic solvent liquid, which is flammable, has slight anesthetic properties, and is non-toxic. If it gets on the skin, wash it off with water.
