Abstract
The disclosure provides a sample testing method and a sample analyzer, the method including: providing a sample and a reagent, the reagent including at least two fluorescent dyes for staining particles in the sample, wherein an absolute value of a difference between wavelengths corresponding to peaks of emission spectra of the two fluorescent dyes is greater than 30 nanometers and less than 80 nanometers, and an overlap between the emission spectra of the two fluorescent dyes is not greater than 50%; mixing the sample and the reagent to form a sample solution; flowing the sample solution in a flow cell in a single test, irradiating the particles flowing in the flow cell using light with a single wavelength; detecting at least fluorescence signals generated by the particles; and obtaining a test result of the sample based on at least the fluorescence signals.
