What are Blood Anticoagulants?
Chemical reagents or substances that can prevent blood coagulation are called anticoagulants, such as natural anticoagulants (heparin, hirudin, etc.), Ca2+chelating agents (sodium citrate, potassium fluoride). The commonly used anticoagulants include heparin, ethylenediaminetetraacetate (EDTA salt), citrate, oxalate, etc. In practical application, the anticoagulants should be selected according to different needs to obtain ideal effects.
Heparin injection is an anticoagulant. It is used to reduce the ability of blood to clot and help prevent harmful clots from forming in blood vessels. This drug is sometimes called a blood thinner, although it does not actually dilute the blood. Heparin does not dissolve blood clots that have already formed, but it can prevent them from getting bigger, which can lead to more serious problems.
Heparin is used to prevent or treat certain vascular, heart and lung diseases. Heparin is also used to prevent blood coagulation during open-heart surgery, heart bypass surgery, kidney dialysis and blood transfusion. It is used in low doses to prevent thrombosis in some patients, especially those who have to undergo certain types of surgery or have to stay in bed for a long time. Heparin can also be used to diagnose and treat a serious blood disease called disseminated intravascular coagulation.
It can only be bought by doctor’s prescription.
A chemical substance that binds certain metal ions, such as calcium, magnesium, lead, and iron. It is used medicinally to prevent blood samples from clotting and to remove calcium and lead from the body. It is also used to prevent bacteria from forming biofilms (thin layers attached to the surface). It is a chelating agent. Also called ethylene diacetic acid and ethylene diethylenediamine tetraacetic acid.
The EDTA-K2 recommended by the International Hematology Standardization Committee has the highest solubility and the fastest anticoagulation speed.
