Abstract

A sample analyzer for analyzing a measurement sample prepared by a sample and a reagent is disclosed. The sample analyzer includes a rotatable first holding section for holding a first reagent container containing a first reagent and a second reagent container containing a second reagent circularly, a rotatable second holding section for holding a third reagent container containing a third reagent and a fourth reagent container containing a fourth reagent circularly, the second holding section being arranged concentrically relative to the first holding section, a dispenser for dispensing a reagent selected from the first to fourth reagents into a measurement sample container for preparing a measurement sample, and a controller. The controller configured to perform operations including receiving an replacement instruction for replacement of the second reagent container, and in response to receiving the instruction for replacement of the second reagent container, if a next reagent to be dispensed is the first reagent and a type of the first reagent is same as a type of the third reagent, controlling the dispenser so as to dispense the third reagent without dispensing the first reagent.
