Problems solved by technology

[0003] During the detection process of existing blood cell analyzers, there may be abnormal conditions such as micropore blockage, unstable liquid flow, unstable power supply, or air bubbles.
Existing hematology analyzers use a single parameter to judge abnormalities, which are prone to failure and cause misjudgments

Abstract

The present application discloses a sample analyzer and a detection method for abnormal counting thereof, wherein the detection method includes: analyzing and processing the counting signal of the particles to obtain a first parameter and a second parameter; judging whether the first parameter is within the first abnormal range; if not, determine whether the second parameter is within the second abnormal range; if yes, determine that the count of the sample analyzer is abnormal. Through the above method, combined judgment can be realized through the first parameter and the second parameter, misjudgment can be avoided, and the accuracy of count abnormality judgment can be improved.

Description

technical field [0001] The present application relates to the technical field of blood cell analysis, in particular to a sample analyzer and a detection method for abnormal counting thereof. Background technique [0002] Impedance method is a common technical method for blood cell analyzer detection. Its main principle is that when blood cells pass through a micropore (such as a gemstone hole), the voltage at both ends of the micropore changes, and then forms a pulse to realize the detection of red blood cells, white blood cells, and platelets. Wait for the blood cells to be detected, that is, count the particles of the blood cells. [0003] In the detection process of the existing blood cell analyzer, there may be abnormal conditions such as micropore blockage, unstable liquid flow, unstable power supply, or air bubbles. Existing hematology analyzers use a single parameter to judge abnormalities, which is prone to failure and misjudgment. Contents of the invention [00...
