La description
There are many kinds of blood anticoagulants in blood collection
tube reagents, and one anticoagulant has a wide range of uses, that
is, potassium EDTA. There are many types of EDTA potassium salt,
among which dipotassium is used more, but what about its principle
and application? There should be some people who are not very
familiar with it. Here we can take a look at what application areas
and principles it has.
EDTA dipotassium salt is also known as dipotassium
ethylenediaminetetraacetate dihydrate (EDTA-K2). It is a white
crystalline powder, easily soluble in water, easy to absorb
moisture, and has a molecular weight of **4.6.
DETA dipotassium salt can protect the cell components of the blood,
does not affect the white blood cells, has the least impact on the
red blood cells, and can inhibit the aggregation of platelets,
which is suitable for general blood tests. But for the separation
test with platelets, it is not suitable for coagulation test and
platelet kinetic energy test, nor is it suitable for calcium ion,
potassium ion, sodium ion, iron ion, alkaline phosphatase, creatine
kinase and leucine amino peptide Enzyme determination and PCR
test.
The EDTA dipotassium salt is mostly used in complexing metal ions
and separating metals, as well as washing powder, shampoo, liquid
soap, agricultural chemical spray, blood anticoagulant and other
fields. The dipotassium EDTA is also recommended by the
International Committee for Standardization in Hematology as the
preferred anticoagulant for blood count and classification.
The principle of EDTA dipotassium salt as an anticoagulant, first
of all, we first understand the principle of blood coagulation,
which can be divided into three parts, 1. The formation of
prothrombin activator, 2. The role of prothrombin activator in
calcium ion With participation, prothrombin is converted into
active thrombin, 3. Soluble fibrinogen is converted into insoluble
fibrin under the action of thrombin. Fibrin is shaped like
filaments, criss-crossed, and collects a large number of blood
cells to form a jelly-like blood clot. This is how coagulation
occurs. The EDTA dipotassium salt has a great affinity for calcium
ions in the blood, and can complex with calcium ions so that
prothrombin cannot be converted into thrombin, thereby making the
blood anticoagulant.
