Abstract
The present invention provides a method for preparing a five-part differential white blood cell control and a white blood cell control prepared thereby. The white blood cell control obtained by the method of the present invention perfectly retains the light scattering properties of every type of white blood cells and has much higher stability than that of real white blood cells, and therefore can be used for the quality control of five-part differential hematology analyzers based on the principle of multi-angle light scattering.
Claims18
A method for preparing a five-part differential white blood cell control, said method comprising the following steps of:
- 1) contacting concentrated blood cells with a hemolytic agent and/or an osmotic regulating agent;
- 2) adding a fixing agent to above mixed solution for conducting fast fixation;
- 3) regulating the concentration of the hemolytic agent and the fixing agent in above mixed solution with an isotonic solution;
- 4) adding the fixing agent to conduct reinforced fixation.
