The Application of High Purity EDTA Tripotassium in Biochemical Detection

Product Details

EDTA tripotassium is a potassium salt of ethylenediaminetetraacetic acid EDTA, which can form chelates with the vast majority of metal ions and become a universal strong chelating agent. It is used for extraction, cation exchange, rare element separation, capacity analysis of calcium, magnesium, and barium, softening in hard water, and as a masking agent, metal cleaning agent, detoxifying agent for heavy metal poisoning, fungicide, and other aspects.

High purity EDTA tripotassium 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 established by the International Committee on Blood Standards (ICSH) in 1993 and widely used. The use of EDTA-K3 anticoagulant for blood analysis in China has not been a long time, and there are few reports on EDTA dependent platelet pseudoreduction. Some studies have shown that when using EDTA-K3 anticoagulant for blood analysis, unexplained low platelet count results were found. Therefore, the patient should undergo manual examination of blood slides and PLT count review, or directly use an instrument for blood cell analysis after diluting non anticoagulant peripheral blood to recheck PLT count, To have a correct understanding of the patient's true level of PLT. Especially for patients with tumors, autoimmune diseases, pulmonary heart disease, pregnant women, advanced liver diseases, and other diseases.
