Abstract: Disclosed is a particle analysis method for identifying infections, comprising: step A of irradiating light on a measurement sample prepared by mixing a test blood specimen containing particles, collected from a subject, a fluorescent dye that stains a nucleic acid, and a hemolytic agent, thereby acquiring scattered light and fluorescence from each particle contained in the measurement sample, step B of specifying particles that are substantially not contained in blood of control subjects not suffering from infection and are determined to be neutrophils contained in blood of patients with infection, based on the scattered light and the fluorescence, and acquiring particle number information on the specified particles, and step C of determining whether the test blood specimen is a specimen collected from patients with bacterial infection or a specimen collected from patients with viral infection, based on the particle number information.
