Complete Solution for Unit Conversion of Heparin Sodium

Hello, I would like to inquire about the potency of your company's heparin sodium
Interviewer: "There are many types and levels of heparin sodium, and the higher the potency, the more expensive the price. I wonder what level of heparin sodium you are consulting about
Regarding the above conversation, many people are confused about the word "valence". Most people have heard of mg, ml, etc., but they do hear very little about the measurement units mentioned above. Heparin sodium, as a naturally advantageous anticoagulant, is widely used in blood testing. Therefore, it is necessary to clarify the unit conversion of heparin sodium.
Before figuring out the unit conversion, we first need to know the relevant content involved and their corresponding measurement units: blood collection vessel specification ml; Addition dose of heparin IU; Corresponding weight of heparin sodium mg; Additive volume ul; The concentration of heparin solution is mg/ml or g/l. The recommended dosage range in the vacuum blood collection industry standard is 12-30IU of heparin sodium per milliliter of blood. Peripheral blood collection for anticoagulation can be less than 14IU per milliliter of blood. Next, we will provide a more intuitive explanation of unit conversion in the form of a table.

Unit conversion:
Weight unit: 1g=1000mg; 1kg=1000g
Volume unit: 1ml=1000ul; 1l=1000ml
From the table above, first of all, we can clearly know that adding 15IU of heparin per milliliter of blood meets the standard. The heparin potency is equal to the dosage of heparin added IU/corresponding weight of heparin sodium (mg) 30 ÷ 0.2=45 ÷ 0.3=150IU/mg. Basically, the higher its potency, the higher its price. Heparin concentration=corresponding weight of heparin sodium/additive volume 0.2/1000 (g) ÷ 20/1000/1000 (l)=0.2 × 1000÷20=10g/l。 Once these are clarified, we can perform conversions backwards and forwards. So if we are clear about what purity of heparin we want, we will raise the issue at the beginning of the article when purchasing it.
Desheng's heparin sodium has a conventional potency of 150-180IU/mg, and as one of the best-selling products, its orders are constantly flowing. Our products have been tested by the market and time, and their positive reviews have also been passed down through word of mouth.
