Which is more suitable as blood cell count anticoagulant

Details:

There are many additives in blood collection vessels, such as anticoagulants and coagulants. Dipotassium and Tripotassium EDTA are often used as anticoagulants in blood collection vessels. Their appearance is white powder and soluble in water. They are mainly used for in vitro anticoagulation of blood. They are anticoagulant additives for clinical blood testing. They are used for pretreatment of blood samples in the process of clinical blood collection and testing.

Whether dipotassium or Tripotassium is more suitable as anticoagulant in blood cell count is still controversial. Some people have done experiments to compare the anticoagulant effects of dipotassium and Tripotassium on normal blood. It is found that there is no significant difference between the two anticoagulants under the best conditions (appropriate anticoagulant concentration and measurement between 1 and 4 hours after bleeding). However, under less ideal conditions, there will be obvious differences. When measured on centrifuged blood, the compacted cell volume decreased with the increase of anticoagulant concentration, which was most obvious in blood samples containing three potassium anticoagulants.

Therefore, the International Committee on blood standards recommends the use of potassium ethylenediamine tetraacetate (EDTA-2K) anticoagulant for whole blood cell count. Using ethylenediamine tetraacetic acid dipotassium salt dihydrate (EDTA-2K) as anticoagulant in vacuum blood collection can preserve leukocyte enrichment in a short time, prevent platelet aggregation and preserve platelets.
