What is Tripotassium EDTA

Release time:


Tripotassium EDTA, also known as tripotassium ethylenediaminetetraacetate, referred to as EDTA-K3, is a chemical substance. It is also a chemical raw material. The molecular formula is C10H13K3N2O8. This product is a white crystalline powder, odorless, easily soluble in water, easy to absorb moisture, and molecular weight is 442.56.



The main purpose

It is used for extracorporeal blood anticoagulation. It is an anticoagulant additive for blood testing clinically. The pretreatment (anticoagulation treatment) of blood specimens is carried out in the process of clinical blood collection and testing.


Scope of application

EDTA salt can protect the cell components of the blood, does not affect the white blood cell count and size, has the least effect on the morphology of red blood cells, and can inhibit the aggregation of platelets, which is suitable for general hematology tests. Except for the separation and testing of platelets, it is not suitable for coagulation tests and platelet kinetic tests, nor is it suitable for calcium, potassium, sodium, iron, alkaline phosphatase, creatine kinase and leucine aminopeptidase The determination.


As a blood anticoagulant, EDTA tripotassium salt has higher solubility and faster anticoagulant speed compared with EDTA dipotassium.
