Common problems of heparin sodium in blood collection

Details:

1. What tests are heparin sodium test tubes suitable for

Clinically, it is mainly used to prevent and treat thrombosis or embolic diseases and diffuse intravascular coagulation caused by various causes; It is also used in hemodialysis, cardiopulmonary bypass, catheterization, microvascular surgery and other operations, as well as the anticoagulant treatment of some blood samples or instruments. Similarly, heparin sodium test tube itself contains heparin sodium, which is mainly used to store anticoagulant blood products.

2. What is the usage of heparin sodium

The general practice is to apply heparin sodium to the pipe wall and put it in the oven for drying before use.

3. What is the purpose of drying Can I use it directly without drying

Drying is mainly to reduce the influence of heparin volume on drug concentration in plasma. It can also be used directly without drying.

4. Is heparin sodium resistant to high temperature

Heparin is generally resistant to high temperature. When drying, it can be dried in an oven at 80 ~ 100 ℃. Dried heparin is best used immediately,

Generally not more than a week.

5. When heparin anticoagulant is used to determine the content of total protein in blood, why is it best to take serum as a sample

After heparin sodium anticoagulant is added to the blood, it blocks the production of thromboplastin and blood coagulation, so that fibrinogen cannot be hydrolyzed and transformed into fibrin monomers, which effectively prevents the formation of fibrin monomers, which remain in the plasma. Serum is blood. After coagulation, fibrinogen is hydrolyzed and transformed into fibrin monomer, which is consumed due to coagulation. After centrifugation, it is separated with blood cells. Therefore, the total protein mass in plasma is all proteins including fibrinogen, while the total protein content in serum without fibrinogen should be lower than the total protein content in plasma in theory. Therefore, when determining the total protein content of blood, it is best to take the serum as the sample for some emergency samples or some patients

For patients in urgent need of determination for other reasons, when the total protein needs to be measured with plasma as a sample, the content of fibrinogen (generally 3% ~ 5%) should be deducted after the total protein is measured, so as to be consistent with the total protein content measured with serum as a sample and truly reflect the actual total protein content in patients.
