Patent ID: 7633604

Claim:
A sample analyzer comprising: a detection unit which irradiates a biological sample with light and obtains optical information: a cell classifier which classifies cells contained in the biological sample into cell groups based on the optical information, the cell groups comprising a reticulocyte group and a mature erythrocyte group; a scattered light information obtainer which obtains first scattered light information relating to reticulocytes included in the reticulocyte group and second scattered light information relating to mature erythrocytes included in the mature erythrocyte group; a calculator which calculates a first component value corresponding to an amount of hemoglobin contained in the reticulocytes included in the reticulocyte group based on the first scattered light information, and a second component value corresponding to an amount of hemoglobin contained in the mature erythrocytes included in the mature erythrocyte group based on the second scattered light information, and which processes the first component value and the second component value; and an output device which outputs the processed result by the calculator.
