EDTA K3 Cas 65501-24-8 High Purity ≥99.5% EDTA Salts
Tripotassium ethylenediaminetetraacetic acid is a kind of potassium salt of ethylenediaminetetraacetic acid EDTA. It can form superfluous compound with most metal ions and become a general-purpose strong superfluous agent, used for extraction, cation exchange, rare elements Separation, volumetric analysis of calcium, magnesium, and barium, hard water softening, and use as a masking agent, metal cleaning agent, antidote for heavy metal poisoning, and a bactericide.

The structure of tripotassium ethylenediaminetetraacetate (EDTA-Tripotassium)
High-purity tripotassium ethylenediaminetetraacetate is usually used as an anticoagulant in vacuum blood collection tubes for blood cell analysis. The use of ethylenediaminetetraacetic acid (EDTA) salt as an anticoagulant for blood cell analysis was determined by the International Committee for Blood Standards (ICSH) in 1993 and is widely used.
Using EDTA-K3 anticoagulant blood for blood analysis, there are few reports about EDTA-dependent platelet false reduction. Studies have shown that unexplained low platelet counts are found when using EDTA-K3 anticoagulant blood for blood analysis As a result, the patient should be manually inspected blood slices and PLT manual count review, or the PLT count should be reviewed directly with the instrument for blood cell analysis after dilution with unanticoagulated peripheral blood, in order to correctly understand the patient's true level of PLT. Especially patients with tumors, autoimmune diseases, pulmonary heart disease, pregnant women, advanced liver disease, etc.
In addition to being used as an anticoagulant, tripotassium ethylenediaminetetraacetate is also similar to dipotassium ethylenediaminetetraacetate and disodium EDTA. It can be used with biological buffers such as Tris and MOPS. It can be used as a mask for some divalent metal ions. Agent, complexing agent, etc.
[introduction] What is K3 EDTA?
Potassium salts of EDTA are used as anticougulating agents for the preservation of whole blood. This can then be used for routine haematology tests including Complete Blood Count (CBC), Haemoglobin and Haematocrit, WBC count, RBC count, Platelet count, and HbA1C test. The special formulation also prevents platelet aggregation of the whole blood.
The tubes contain EDTA, preventing blood from clotting by binding calcium ions.
Anticoagulant: EDTA potassium salt (ethylenediaminetetraacetate).
Specimen: whole blood.
Immediately after the specimen is collected, gently invert the EDTA tube 9-10 times to mix thoroughly.
Insufficient mixing could lead to platelet aggregation, microclot formation or coagulation.

P.S.[What is the Difference Between K2 EDTA and K3 EDTA?]
The main difference between K2 EDTA and K3 EDTA is that K2 EDTA contains two chelated potassium ions whereas K3 EDTA contains three chelated potassium ions. Furthermore, K2 EDTA slightly increases the MCV (mean corpuscular volume) of red blood cells at higher concentrations while K3 EDTA has no influence on the MCV of red blood cells at higher concentrations.
K2 EDTA and K3 EDTA are two types of anticoagulants used in routine hematological tests. However, their influence on the blood count remains controversial.
