Patent ID: 8652848

Claim:
A method for analyzing blood cells in a whole blood sample obtained from a cat, the method comprising: acquiring an electrical measurement result and an optical measurement result of the whole blood sample obtained from a cat, the whole blood sample being not hemolyzed; the electrical measurement result indicating a number of particles in at least a part of the whole blood sample for every size of the particles measured by an electrical measurement section, and the optical measurement result including a first optical property and a second optical property for each of at least some of particles in another part of the whole blood sample measured by an optical measurement section; discriminating, on the basis of the first and second optical properties in the optical measurement result, the particles into at least one of a group of red blood cells and a group of platelets; counting the particles in a respective group to determine at least one of a number of red blood cells, a number of platelets and a ratio of the number of red blood cells and the number of platelets; generating a particle size distribution on the basis of the number of particles and the size thereof included in the electrical measurement result; and calculating, on the basis of the particle size distribution generated from the electrical measurement result and the number of red blood cells or platelets or the ratio thereof from the optical measurement result, a mean volume of red blood cells in the whole blood sample obtained from the cat.
