Document Type and Number:
WIPO Patent Application WO/2023/125955
Kind Code:

Abstract:
A blood cell analyzer, a method for alerting of an infection state of a subject, and a use of an infection marker parameter. The blood cell analyzer comprises a sample drawing apparatus (110) that is used for drawing a blood sample to be tested of a subject, a sample preparation apparatus (120) that is used for preparing an assay sample, an optical testing apparatus (130) that is used for testing the assay sample so as to obtain optical information, and a processor (140). The processor (140) is configured to: on the basis of at least two types of light intensity information, generate a scatter plot, on the basis of the scatter plot, calculate an area and/or volume parameter of at least one leukocyte particle mass in the scatter plot, on the basis of the area and/or volume parameter, obtain an infection marker parameter for evaluating an infection state of the subject, and output the infection marker parameter. Thus, an accurate and effective infection marker parameter can be quickly provided, thereby effectively assisting a user to evaluate an infection state of a subject.
