Résumé : The aim of this study is to evaluate the analytical performance of the new Sysmex XN-2000® analyzer in our routine laboratory. Overall, 798 adult and 340 pediatric blood samples were analyzed during a period of 3weeks on the Sysmex XN-2000® and Advia 2120i® as well as 100 body fluids. Analytical parameters as within-run and inter-day precisions, carry-over, linearity, limit of quantification, stability are excellent for the complete blood count (CBC) and correlation with Advia results shows high concordance between most parameters, except for the monocytes counts which are systematically higher with the Sysmex XN-2000®. The body fluids module shows high precision (CV<10%) for WBC with negligible carry-over and excellent linearity. However, the BF module cannot give a number of RBC below 1000μL. RBC results are only provided in interval of 103/μL cells with no intermediate counts. We concluded that the Sysmex XN-2000 provides highly reliable results. However, in our view, improvement of RBC count is mandatory and impairs full-automated counts of this kind of samples. © 2013 .
