The Sysmex XS-1000i® is a new and compact blood analyzer with 5diff technology and fluorescent flow cytometry, technologies hitherto only present in large equipment and available only for laboratory equivalent routines. In this study its performance was compared with equipment for impedance analysis (Coulter T-890®) and the microscopic counting of 200 differential leukocytes. One hundred samples were evaluated in parallel by both apparatuses and subjected to differential counts of 200 cells. The results were analyzed using the Spearman correlation for parametric data showing no correlation greater than 95% for white blood cells, red blood cells, hemoglobin, hematocrit and neutrophils,; correlations between 90% and 94.9% for VCM, MCH, lymphocytes and eosinophils, and correlations lower than the 89.9% for MCHC, monocytes and basophils. The results suggest that this apparatus is a versatile tool for routine analyses in small and medium laboratories. However, in the case of flags, confirmation under a microscope is important to guarantee the quality of the final results.
