Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The invention provides a method for reducing the measurement error of red blood cell parameters. The red blood cell parameters are measured in a blood cell analyzer, and the red blood cells are incubated with a cell diluent, and the temperature change of the diluent is within a fixed range.

[0026] The method provided by the invention can fix the change of the temperature of the cell diluent within a certain range, and the change is not large, so that the parameters of red blood cells can be measured more accurately, and the operation is simple.

[0027] The examples provided below only mea...

Abstract

The invention relates to the technical field of erythrocyte parameter measurement, and provides a method for reducing the measure errors of erythrocyte parameters, and a temperature control device used in the method. The method is characterized in that the erythrocyte parameters are measured in a blood cell analyzer, erythrocytes are incubated in a cell dilution solution, and the temperature change of the cell dilution solution is in a fixed range. The temperature of the cell dilution solution is controlled in the invention, so the change of the temperature of the cell dilution solution in a permitted fixed range is guaranteed, thereby the change of the conductivity of the cell dilution solution is not large, even minimal, a basically-consistent temperature of the cell dilution solution in the erythrocyte parameter measurement through the blood cell analyzer is guaranteed, and the erythrocyte parameter measure accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of red blood cell parameter measurement, in particular to a method for reducing red blood cell parameter measurement error and a temperature control device used in the method. Background technique [0002] In the prior art, in the process of measuring the red blood cell MCV, the red blood cells are incubated with the cell diluent, and the conductivity of the cell diluent will change due to changes in temperature, so that due to the change in the conductivity of the cell diluent , it will lead to large errors in the measurement of red blood cell MCV. [0003] In view of the above defects, several methods are also used in the prior art to improve, but these several methods all have relatively large limitations, as follows: [0004] (1) During the process of measuring red blood cell MCV or other parameters by using the blood cell analyzer, the change law of the temperature of the cell diluent is obtained, so a...
