A comparison of the differential white blood cell count using the Technicon H1, the Technicon H6000 and the Coulter VCS.

One hundred blood samples were analysed on Technicon H1, Technicon H6000, and Coulter VCS hematology analysers, and the white cell differential counts were compared. All three instruments showed very good agreement for neutrophils and lymphocytes, good agreement for eosinophiles, and acceptable agreement for monocytes. For the material analysed there were no disparities of clinical significance between the results obtained from the three instruments.
