Blood analyzer, blood analyzing method, and computer program product

A blood analyzing method, using a blood analyzer which comprises:

• a specimen preparation section for preparing, by using a blood sample obtained from a subject, a measurement specimen that is used to measure a white blood cell count among CBC measurement items;
• and a measurement section for obtaining at least two types of optical information from blood cells contained in the measurement specimen prepared by the specimen preparation section by irradiating the measurement specimen with light, the blood analyzing method comprising:
• classifying blood cells contained in the measurement specimen into at least white blood cells and blood cells suspected to be abnormal blood cells contained in the measurement specimen, based on the at least two types of optical information obtained by the measurement section;
• obtaining distribution data of the white blood cells and distribution data of the blood cells suspected to be abnormal blood cells;
• counting the white blood cells contained in the measurement specimen, based on the distribution data of the white blood cells;
• and
• determining presence or absence of the abnormal blood cells in the blood sample, based on the distribution data of the blood cells suspected to be abnormal blood cells.

A computer program product for a blood analyzer which comprises:

• a measurement apparatus for preparing, by using a blood sample obtained from a subject, a measurement specimen that is used to measure a white blood cell count among CBC measurement items, and for obtaining, by irradiating the measurement specimen with light, at least two types of optical information from blood cells contained in the measurement specimen;
• and a computer, the computer program product comprising:
• a computer readable medium for storing instructions enabling the computer to carry out operations comprising:
• classifying blood cells contained in the measurement specimen into at least white blood cells and blood cells suspected to be abnormal blood cells contained in the measurement specimen, based on the at least two types of optical information obtained by the measurement section;
• obtaining distribution data of the white blood cells and distribution data of the blood cells suspected to be abnormal blood cells;
• counting the white blood cells contained in the blood sample, based on the distribution data of the white blood cells;
• and
• determining presence or absence of the abnormal blood cells in the blood sample, based on the distribution data of the blood cells suspected to be abnormal blood cells.
