9045-22-1 Green Tube Lithium Heparin For Vacuum Blood Collection Tube

Heparin is a mucopolysaccharide containing sulfuric acid groups extracted from the intestinal mucosa of animals. It is a biologically active substance with a strong negative charge. Lithium heparin has the effect of activating antithrombin III and inactivating serine protease in the blood, thereby preventing the formation of thrombin and preventing platelet aggregation and other anticoagulant effects. So how do we solve the following problems when we use it?

1. What is the difference between heparin sodium and lithium heparin as a blood collection tube?

Answer: The binding ions are different: Although both lithium heparin and sodium heparin are anticoagulated blood and are also a combined form of heparin, the effective ion binding is different, which also makes the appearance look the same Lithium heparin and sodium heparin are essentially different in texture, and their dissociation degree is also different. It can be said that heparin lithium is replaced from heparin sodium.

The dosage added to the blood collection tube is different: the actual use of heparin lithium and heparin sodium is still in the vacuum blood collection tube, while the dosage range of heparin lithium in the industry standard is 9.4IU~28IU unit/ml, and heparin sodium is per ml of blood. 12IU~30IU. The amount of lithium heparin and sodium heparin in one milliliter of blood in a venous vacuum blood collection tube is 15IU-20IU.

2. What grade is required for lithium heparin used in blood collection tubes?

Answer: The lithium heparin in the blood collection tube requires biochemical grade heparin lithium.

3. As an additive for common blood routine tubes, what is the recommended dosage of lithium heparin?

Answer: The general recommended dosage is 15-25IU per ml of blood, and the recommended dosage is 20IU/ml. The specific usage can be carried out according to the actual situation.

4. Why do some lithium heparin tubes show tiny coagulation fragments after blood sampling?

Answer: This is because the local anticoagulant concentration in the lithium heparin anticoagulant tube is too high, which causes part of the blood to enter the blood collection tube and cannot be fully mixed with the lithium heparin, which results in some small clots. This may be caused by the failure to invert and mix the test tube in time after blood sampling.

5. In addition to being used as an additive for green headgear, can lithium heparin be used as an additive for other tubes?

Answer: Yes. It can be used in conjunction with sodium fluoride and separating glue. When lithium heparin is used in combination with sodium fluoride, it can be used in blood glucose tubes, adding about 20IU per milliliter of blood. When lithium heparin is used in combination with separation gel, the dosage of lithium heparin remains unchanged, and 0.8-1.2 grams of separation gel can be added to each tube.

6. What are the storage conditions for lithium heparin?

Answer: This product can be sealed and stored in a cool and dry place, protected from light and protected from moisture. The aqueous solution of this product can be sealed and stored at 0-4°C in a sterile state, and the maximum shelf life should not exceed 7 days. It is recommended that the aqueous solution of this product be used immediately after preparation, and do not store it in a solution state for a long time. It is forbidden to use heparin lithium when there are foreign matter, abnormal smell, color and effective shelf life.
