Blood cell analyzing instrument and recognizing method and system for abnormal cells thereof

Abstract

The invention discloses a recognizing method for abnormal cells. The method includes steps of: (1) per-grouping to-be-test cells; (2) obtaining a signal which reflects size information of the to-be-test cells and converting the signal into a first electronic pulse, and calculating to obtain an equivalent width of the first electronic pulse; and (3) comparing the equivalent width of the to-be-test cells in one cell group with a preset value of the cell group, if the equivalent width is more than the preset value, recognizing the to-be-test cells as the abnormal cells in the corresponding cell group. Because that an upper limit of the equivalent width of normal cells is certain, cells in the cell group, in which the equivalent width is more than the preset value, is recognized as the abnormal cells. By means of the method, accuracy of recognizing the abnormal cells can be improved. In addition, the blood cell recognizing method is carried out through calculation to obtain the equivalent width of the electronic pulse on the basis of a conventional light scattering method for obtaining the electronic pulse so that the method is free of individual detection channels, thereby reducing complex degree of the instrument and enabling the instrument to be more small-sized.

Description

technical field [0001] The invention relates to blood analysis, in particular to a blood cell analyzer and a method and system for identifying abnormal cells thereof. Background technique [0002] Blood cell analyzers are generally used to count and classify red blood cells, platelets, and white blood cells in the blood. Among them, five-differentiation blood cell analyzers generally divide white blood cells into five categories: lymphocytes, monocytes, neutrophils, eosinophils, and basophils. Subgroup, when there are atypical abnormal lymphocytes and immature white blood cells in the white blood cells, the blood cell analyzer will give an abnormal alarm prompt. [0003] Generally, the method of classifying white blood cells into five categories is the light scattering method, the basic principle of which is to use light scattering signals at two or more angles to detect blood cells dynamically flowing through the flow chamber, usually with a lower scattering angle The sign...

AI Technical Summary

Problems solved by technology

Due to the overlapping of abnormal cells and normal cells, the above-mentioned light scattering method has the disadvantage of low accuracy in identifying abnormal cells in blood.
