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, in particular 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 the blood cell analysis, the cleaning solution and the diluent cooperate to clean the container and pipeline of the instrument detection unit, so as to reduce the background value of the instrument and avoid the interference of the previous test sample on this test. In addition, the diluent also maintains the original shape of white blood cells and platelets, and ensures that the instrument can accurately classify white blood cells. [0003] The diluent currently used has the following disadvantages: the components in the diluent are prone to settle due to gravity for a long time, resulting in the osmotic pressure of the bottom layer of the dil...
