Time-dependent changes in cell population data obtained using Sysmex XN-series hematology analyzer in bacterial infections.

Background: Time-dependent changes in cell populations during acute bacterial infections remain unclear. We assessed time-dependent changes in fluorescent light intensity of the neutrophil area (NE-SFL) and fluorescent light distribution width index of the neutrophil area (NE-WY) and their association with sepsis and bacteremia.

Methods: Patients with acute bacterial infections were enrolled in this prospective, observational cohort study.
