EDTA salts (ethylenediaminetetraacetic acid) are used to anticoagulate whole blood for haematological investigations as the cellular components of the blood are particularly well preserved by EDTA. It works as an anticoagulant as it forms complexes with metal ions such
as calcium, therefore inhibiting the coagulation cascade.Anticoagulation with EDTA is irreversible.

The EDTA concentration in BD Vacutainer® Tubes is 1.8 mg per mL of complete blood when the fill level is correct, as recommended by the ICSH (International Council Society of Haematology)1. The ICSH recommends dipotassium EDTA salt (K2EDTA) for haematological
investigation. BD Vacutainer® plastic tubes are available with spray dried K2EDTA and K3EDTA.
