A particle measuring method, a sample processing method, and a particle imaging apparatus capable of efficiently acquiring information effective in pathological diagnosis or the like are provided. The particle measuring method comprises a step (S) of labeling and amplifying, within a particle, a target nucleic acid in the particle, a step (S) of labeling a surface target polypeptide on the surface of the particle and/or target nucleic acid different from the first target nucleic acid, and a step (S) of measuring the labeled target nucleic acid and the labeled target polypeptide and/or other labeled target nucleic acid.

Particle measuring method, sample processing method, and particle imaging apparatus

Disclosed is a specimen pretreatment apparatus comprising: a specimen container holder configured to hold a specimen container for containing a plasma specimen; a reagent container holder configured to hold a first reagent container for containing a first reagent including magnetic particles on which a nucleic acid in the plasma specimen is adsorbed; a reaction unit in which a plurality of reaction containers are disposed, the reaction unit being configured to accelerate, in each reaction container, reaction of the plasma specimen and the first reagent; a washing unit in which a washing container is disposed, the washing unit including a magnetic force applying portion configured to apply magnetic force to the washing container; a dispensing unit; and a controller programmed to control the dispensing unit to: dispense the plasma specimen contained in the specimen container and the first reagent into the plurality of reaction containers in the reaction unit; dispense a mix liquid of the plasma specimen and the first reagent from each of the plurality of reaction containers into the washing container; and remove a liquid component from the washing container while the magnetic particles contained in the discharged mix liquid is attracted by the magnetic force applying portion.
