Abstract:
We describe two cases of chronic lymphocytic leukemia (CLL) with spuriously increased neutrophil count by the Sysmex SE-9000 hematology analyzer. Each case showed an excess of small lymphocytic cells in blood film microscopy, and a large group of plots in the lymphocyte area was observed on the differential scattergram of the SE-9000. In the cases of CLL, there is a possibility of overestimation of neutrophil count by the SE-9000. Microscopic examination and review of differential scattergram of the SE-9000 are necessary in the cases with increased leukocyte count.
