Sample testing method and sample analyzer

Abstract

The disclosure provides a sample testing method and a sample analyzer, the method including: obtaining a sample to be tested; providing a reagent, the reagent including a hemolytic agent, a first fluorescent dye and a third fluorescent dye; mixing the sample and the reagent to form a sample solution; making the sample solution flow in a flow cell in a single test, irradiating the particles by using a first light source and a second light source, and detecting scattered light signals, first fluorescence signals and third fluorescence signals; obtaining a classification result and/or a counting result of white blood cells in the sample to be tested based on the first fluorescence signals and the scattered light signals; and obtaining a counting result of nucleated red blood cells in the sample to be tested based on the third fluorescence signals and the scattered light signals.
