What is the use of dipotassium ethylenediaminetetraacetic acid in EDTA tube

EDTA tubes are also called anticoagulant tubes, and the cap color of the tubes is purple. In recent years, with the popularization of blood testing and analysis , EDTA tubes are widely used in clinical medicine, and are often used in conjunction with dipotassium ethylenediaminetetraacetic acid. EDTA-2K for short, because it can inhibit the aggregation of platelets, so as to achieve the purpose of blood anticoagulation. Next, we will introduce the use of dipotassium ethylenediaminetetraacetic acid in EDTA tubes in detail.

Dipotassium EDTA is a metal ion chelating agent, because blood contains calcium ions, so it has a great affinity, and can effectively chelate calcium ions in blood samples, so that prothrombin cannot be converted into thrombin, thereby To prevent coagulation of blood samples, usually every 0.8mg can anticoagulate 1ml of blood.

Dipotassium EDTA parameters:

As an anticoagulant additive in EDTA tubes, 20 μl of an aqueous solution containing 200 g/L of dipotassium ethylenediaminetetraacetate is usually preset in each EDTA tube in order not to affect the blood due to the low concentration when adding it.

However, it should be noted that sometimes the service life of the EDTA tube and the environment are affected. For example, when the temperature changes, the water is easy to evaporate to the tube wall, especially in the plastic tube. The moisture of the solvent can seep through the tube wall and leak out. Dipotassium EDTA crystallized in the tube.

When the crystallized EDTA tube is used for blood collection, the medical staff need to shake it up and down slowly about 8 times, so that the blood can fully contact the crystallized dipotassium ethylenediaminetetraacetic acid, so as to play an anticoagulant effect, otherwise it will lead to inaccurate test results .

In the process of adding dipotassium ethylenediamine tetraacetate to the EDTA tube for anticoagulation, it can store the growth of white blood cells in a short period of time, which can not only prevent platelet aggregation, but also preserve platelets, so it is recommended by the International Blood Standards Committee.

On this basis, various suppliers came into being. Desheng Biochemical is a manufacturer of dipotassium ethylenediaminetetraacetate. It has been in production for several decades. Complete, including serum separation gel, heparin sodium, heparin lithium, EDTA dipotassium, tripotassium, disodium, etc., have been exported to many countries around the world, and are often praised by customers.
