Patent ID: 7936456

Claim:
A particle analyzer for analyzing a particle in a sample, comprising: a detecting section configured to detect each of particles contained in a first measurement sample prepared from a sample and a first reagent, and detect each of particles contained in a second measurement sample prepared from the sample and a second reagent different from the first reagent; and a controller configured to perform operations comprising: acquiring at least a first and a second characteristic information of each of the particles contained in the first measurement sample based on a first detection result obtained from the first measurement sample, and acquiring at least a third and a fourth characteristic information of each of the particles contained in the second measurement sample based on a second detection result obtained from the second measurement sample; obtaining a particle number of a specific kind of particles contained in the sample based on at least the acquired first and second characteristic information, and obtaining each particle number of a plural kinds of particles contained in the sample based on at least the acquired third and fourth characteristic information, the plural kinds of particles being different from the specific kind of particles, determining a target kind of particles, whose particle number is corrected, from the plural kinds of particles, based on at least the acquired third and fourth characteristic information; and correcting the obtained particle number of the target kind of particles by using the obtained particle number of the specific kind of particles.
