Diluent for blood cell analyzer

Abstract

The invention provides a diluent for a blood cell analyzer. The diluent consists of edentate, sodium sulfate, sodium chloride, dimethylol urea, biological buffer, a betain type nonionic surfactant, sodium azide and water. The diluent solves the problems that the osmotic pressure of a bottom layer is higher than that of an upper layer and the solution is not uniform or stable when the diluent for the blood cell analyzer stands for a long time.

Description

Technical field [0001] The invention belongs to the field of blood cell analysis, and in particular relates to a diluent for a blood cell analyzer. Background technique [0002] Diluent is the most commonly used reagent for blood cell analyzers in clinical testing and is a key reagent for completing blood cell classification or counting. Before blood cell analysis, the cleaning solution and diluent work together to clean the container and pipes of the instrument detection unit, thereby reducing the background value of the instrument and avoiding interference from the previous test sample on this test. In addition, the diluent also plays a role in maintaining the original shape of white blood cells and platelets and ensuring that the instrument can accurately classify white blood cells. [0003] The currently used diluent has the following shortcomings: the components in the diluent are prone to sedimentation due to gravity when left for a long time, resulting in the osmotic...

AI Technical Summary

Problems solved by technology

[0003] The currently used diluent has the following disadvantages: the components in the diluent are easy to settle due to gravity after being placed for a long time, resulting in the osmotic pressure of the bottom layer of the diluent being significantly higher than that of the upper layer, and the solution is not uniform and stable, which in turn causes the histogram of white blood cells and red blood cells Left shift, false increase in percentage of lymphocytes, etc.
