Common problems of heparin lithium in vascular collection

Details:

1. Why do more than 100 domestic blood collection manufacturers choose heparin lithium produced by Desheng

A: Desheng's heparin lithium is produced by itself. It has independent intellectual property rights and the production process is fully traceable and controllable. Based on the business philosophy of morality and honesty, Desheng heparin lithium has the characteristics of high purity, accurate titer, accurate colony control range and so on.

2. Heparin lithium and heparin sodium are both additives for green head cap blood collection, so what is the difference between the two

A: there are three commonly used heparin sodium salts: ammonium, lithium and sodium. Heparin lithium is the most suitable heparin because it has the smallest effect on the test of other ions. Heparin lithium basically contains no excess ions. It should not be used to test lithium levels in blood collection vessels. Secondly, the anticoagulant effect of heparin sodium is less delayed than that of heparin lithium. Heparin is the only anticoagulant that can be used to determine pH, blood gas, electrolyte and calcium ion.  

3. Why do some heparin lithium tubes have tiny coagulation fragments after blood collection

A: This is because the local anticoagulant concentration in the heparin lithium anticoagulant tube is too high, resulting in that some blood cannot be fully mixed with heparin lithium after entering the blood collection vessel, resulting in some micro clots. This may be due to the failure to reverse the mixing tube in time after blood collection.

4. Can heparin lithium be used as an additive for other tubes besides the green cap

A: Yes. It can be used with sodium fluoride and separation gel. When heparin lithium is used in combination with sodium fluoride, it can be used for blood glucose tube, adding about 20iu per ml of blood. When heparin lithium is used with separation gel, the addition dose of heparin lithium remains unchanged, and 0.8-1.2g of separation gel can be added to each branch pipe.
