technical field
[0001] The invention relates to the field of medical equipment, in particular to a blood cell analysis method and a blood cell analyzer. Background technique
[0002] In recent years, blood cell analyzers that use flow cytometry to count and classify blood cells have come out one after another. Traditional blood cell analyzers use Coulter's principle (also known as resistance method) to count platelets, but are susceptible to the influence of small red blood cells and red blood cell fragments. In recent years, the method of counting platelets using fluorescent dyeing and laser scattering, also known as platelet optical counting method, has emerged. The principle is to generate photoelectric signals through laser irradiation on cells treated with fluorescent reagents. Different photoelectric signals can reflect the physical and chemical characteristics of cells, such as cell size, granularity, and expression of antigen molecules, so that different types of ce...
