Blood cell analyzer for detecting archaeocyte and detection method

A sample analysis method, comprising:

• receiving an operation instruction to perform a blast testing on a sample;
• wherein the blast testing comprises:
• aspirating the sample, comprising aspirating at least part of the sample as a first sub-sample;
• processing the sample, comprising mixing the first sub-sample with a first type of reagents to obtain a first sample to be tested;
• wherein the first type of reagents comprises a first reagent comprising a first hemolytic agent and a second reagent, the first reagent comprising a fluorescently labeled antibody, the first hemolytic agent being mixed with the first sub-sample for no more than 2 minutes, and the fluorescently labeled antibody being capable of binding to an antigen of a surface of a blast;
• detecting the sample to be tested, comprising passing particles in the first sample to be tested through a detection region of an optical detection device one by one and irradiating the particles in the first sample to be tested using a light source of the optical detection device, to obtain a scatter signal and a fluorescence signal of the first sample to be tested, the scatter signal comprising a first side scatter intensity signal from the first sample to be tested, and the fluorescence signal comprising an antibody fluorescence intensity signal from the fluorescently labeled antibody;
• and
• obtaining particle information, comprising obtaining particle information of the first sub-sample based on the first side scatter intensity signal and the antibody fluorescence intensity signal, the particle information of the first sub-sample comprising blast information.
