Tripotassium EDTA / EDTA K3 anticoagulation of blood samples

Tri-potassium EDTA / EDTA K3

Content:







[Pr , oduct Name] Tri-potassium EDTA

[Formula] EDTAK3·2H2O

[Package Specification] Plastic bottle, 500g/bottle

[Performance] White crystal powder, odorless, soluble in water, easy to absorb
moisture, molecular weight of 442.56, pH value of 7.3±1 (5% aqueous solution,
g/ml,), solubility in water ≥60% (g/ml, at 25℃). Stable at room temperature. The
main content of tri-potassium EDTA ≥99.0%. See the product test report for other
indicators.

[Application] This product is specially used for in vitro anticoagulation of
blood, and is an anticoagulant additive for clinical blood test. It is used for
blood sample pretreatment (anticoagulation treatment) in the process of clinical
blood collection and test.

[Scope of application] EDTA salt can protect the cellular components of the blood,
does not affect the white blood cell count and size, has the least effect on the
red blood cell morphology, and can inhibit the aggregation of platelets, suitable
for general hematological tests. Except for the isolation and examination of
platelets, it is not suitable for coagulation test and platelet kinetic energy
test, nor for the determination of calcium, potassium, sodium, iron, alkaline
phosphatase, creatine kinase and leucine amino peptidase and PCR test. 

The international committee for standardization of hematology (icsh) recommends
the preferred anticoagulant for blood counts and classification of tripotassium
EDTA. Compared with dipotassium EDTA, it has higher solubility and faster
anticoagulation rate.
