What differences can I expect to see in hematological parameters when I switch from BD Vacutainer® K3EDTA to BD Vacutainer® K2EDTA?
K3EDTA is a liquid and will dilute the sample ~ 1-2%. K2EDTA is spray-dried on the walls of the tube and will not dilute the sample. Slightly higher results have been seen from the K2EDTA tube in some CBC parameters, but none of these were clinically significant. It is important to mix the sample 8 – 10 times immediately after collection to ensure all the anticoagulant is thoroughly mixed with the blood sample.
