Becton Dickinson evacuated blood collection tubes are sterile, single-use and contain tripotassium (K3) or dipotassium (K2) EDTA (Ethylenediamin tetra-acetic acid) for whole blood determinations in haematology.
The EDTA inhibits the coagulation process by eliminating the calcium in the blood, reducing the platelet activation by protecting the platelets when the blood comes into contact with the inner surface of the tube. Ideal for counting leucocytes, platelets and red blood cells or for determining the leucocytic formula, for flow cytometry and for determinations of lead as the morphologies of the blood cells are preserved.
