Application of high purity potassium EDTA in biochemical detection

Details:

Potassium EDTA is a potassium salt of EDTA. It can form a complex with most metal ions and become a universal strong complex agent. It is used for extraction, cation exchange, separation of rare elements, volumetric analysis of calcium, magnesium and barium, softening of hard water, and as a masking agent, metal cleaning agent, antidote and bactericide for heavy metal poisoning.

Structure of Tripotassium EDTA

High purity potassium EDTA is usually used as an anticoagulant in vacuum blood collection vessels for blood cell analysis. The use of ethylenediamine tetraacetic acid (EDTA) salt as an anticoagulant for blood cell analysis was determined by the International Committee on blood standards (ICSH) in 1993 and is widely used. In China, it is not long to use edta-k3 anticoagulant for blood analysis, and there are few reports on EDTA dependent pseudothrombocytopenia. Some studies have shown that when using edta-k3 anticoagulant for blood analysis, it is found that the platelet count is too low for unknown reasons. The patient should check the blood tablets and PLT manual count manually, or directly use the instrument for blood cell analysis after dilution of non anticoagulant peripheral blood to recheck the PLT count, To correctly understand the true level of PLT of patients. Especially tumor patients, patients with autoimmune diseases, cor pulmonale, pregnant women, advanced liver diseases and so on.

In addition to the divalent EDTA, potassium EDTA and other biological masking agents, EDTA can also be used as some divalent EDTA, potassium EDTA and other biological masking agents.

Desheng has been committed to the research of EDTA potassium salt, a blood collection additive, since 2005. Among them, the quality of EDTA two potassium and EDTA three potassium products is excellent. They have stable sales at home and abroad and are highly praised by our customers!
