Cell analyzer and its red blood cell agglutination alarm method and system

Abstract

A cell analyzer and its erythrocyte agglutination alarm method and system, which measure the volume information of cells in a sample to be tested, identify cells whose volume information in the sample to be tested is greater than a preset volume threshold, obtain agglutinated red blood cell groups, and count the agglutinated red blood cell groups The number of cells was obtained to obtain the amount of erythrocyte agglutination. It is judged whether the amount of red blood cell agglutination is greater than the preset number threshold, and if the amount of red blood cell aggregation is greater than the number threshold, an alarm for red blood cell agglutination is performed. Since the agglutinated erythrocytes are identified directly according to the cell volume, it is not necessary to judge according to the content of specific components in the cells. Compared with the traditional erythrocyte agglutination alarm method, the alarm accuracy is improved, and it is simple and fast.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a cell analyzer and a red blood cell agglutination alarm method and system thereof. Background technique [0002] At present, medical particle analyzers have been widely used in the field of medical testing. For example, blood cell analyzers have become an important means of replacing microscopic examinations for blood routine analysis. Take the measurement of red blood cells as an example. Under normal circumstances, red blood cells are evenly distributed in the blood. However, when the sample has defects such as abnormal cold agglutinin content or the blood collection process is not standardized, the red blood cells evenly suspended in the blood may aggregate into clumps, resulting in red blood cells. of agglutination. Red blood cell agglutination will interfere with the measurement results of the hematology analyzer, and at the same time, it is necessary to pay atte...

AI Technical Summary

Problems solved by technology

When the sample is a hypochromic sample, the MCHC value when the sample does not agglutinate is lower than the normal reference range. When the sample has RBC agglutination, the MCHC value rises, but it is still within the reference range of a healthy person. At this time, it will not be given RBC agglutination alarm; in addition, for some hyperpigmented samples, the MCHC value itself is higher than the reference range of healthy people, and it is easy to be judged as a mismatch between RBC and HGB, so it is falsely alarmed as RBC agglutination

[0004] Therefore, the traditional alarm method has the disadvantage of low accuracy
