Dfference between sodium heparin and lithium heparin
Heparin, as a natural anticoagulant substance, is extracted from pig intestinal mucosa and then chemically produced into heparin sodium or heparin lithium. Among them, they are most commonly used as in vitro anticoagulants when added to test tubes. Although their uses are consistent and the finished products are all white powder in appearance, it does not mean they are the same. Therefore, the following will introduce the differences between heparin sodium and heparin lithium in detail.

1、 The difference between the two binding ions
Although they all exist in the form of heparin, there are obvious differences in ionic structure, which makes heparin sodium and heparin lithium almost identical in appearance, but fundamentally different. In addition, different binding ions represent different degrees of dissociation, and the heparin lithium produced by Desheng is obtained by replacing it with heparin sodium.
2、 The dosage of heparin sodium and heparin lithium is different
They can be added to vacuum blood vessels as anticoagulants, but they need to be added according to industry standards after being prepared into a solution, and the dosage of the two is different. The standard dosage range for heparin sodium in the industry is 9.41-281U units/milliliter, while the additive amount for heparin sodium is 121U-301U per milliliter of blood.
3、 Differences in white blood cell count results in biochemical testing
In the routine test report, it can be intuitively seen that heparin sodium and heparin lithium have different white blood cell count results for the same sample. The manifestation pattern of heparin sodium is more obvious, and it can change over time. For example, over time, the white blood cell count increases at a constant temperature and then decreases. However, the decrease in white blood cell count detected by heparin lithium is not significant, and the entire process changes slowly and steadily.

4、 The prices of heparin sodium and heparin lithium are different
You can find that the prices of heparin sodium and heparin lithium are different when purchasing online or looking for manufacturers to supply, with heparin lithium being more expensive than heparin sodium. This is mainly because on the one hand, heparin lithium is replaced from heparin sodium, and on the other hand, heparin lithium has the least interference with certain experiments.
The difference between heparin sodium and heparin lithium can be clearly seen from the above four aspects, and everyone should pay attention to distinguishing when using them. In addition to heparin sodium and heparin lithium, commonly used anticoagulants include EDTA potassium salt, sodium citrate, etc. Desheng, as a professional manufacturer of raw materials for blood sampling additives, is involved in all the aforementioned products. In addition, it also sells flagship products such as biological buffering agents and luminescent reagents. If you are interested, please click on the website to inquire and purchase!
