Summary: | Introduction
The purpose was to evaluate the analytical performances of Sysmex XN 3000 and UniCel DxH 800 comparing the obtained results with manual counting and between each other. Also flagging capabilities of abnormal cells were compared for both analyzers.
Methods
Two thousand one hundred and forty‐two whole‐blood samples were analyzed for evaluation. The samples flagged due to blast, atypical lymphocyte (AL), immature granulocyte (IG), or nucleated red blood cells (NRBC) were microscopically reviewed (n=102).
Results
The within‐run and between‐day coefficient of variations (CV%) of XN 3000 for hemoglobin, RBC, MCV, WBC, and platelets were lower than 5% and for WBC differentials lower than 10% except monocytes which was 15.6% at low level. The precision results of DxH 800 were also lower than 5.0% except platelets (9.5%) and monocytes (45%) at low level. The comparison of analyzers revealed good agreement (R>.86), except monocytes and basophils. The flagging sensitivities of XN 3000 were higher for IGs, blasts, and ALs than those of DxH 800 and almost similar for NRBC.
Conclusion
The XN 3000 and DxH 800 are accurate, highly precise systems and can be used effectively in high‐volume laboratories. The flagging sensitivity of XN 3000 was higher in detecting blasts, IGs, and ALs than that of DxH 800. The detection of abnormal cells with high sensitivity may improve laboratory workflow with a reduced slide review and accelerated turnaround time. |
