Patent ID: 7931863

Claim:
A sample analyzer for analyzing a sample, comprising: a holding section comprising a plurality of holding regions for holding reagent containers, each of the reagent containers containing a reagent, and being capable of moving the holding regions, wherein only a portion of the holding regions are populated with reagent containers; an analyzing unit for analyzing a measurement sample prepared by mixing a sample and the reagent contained in the reagent container held by the holding section; a reader for reading identification information attached to a reagent container held by the holding section; an input device; a display; a controller configured to perform operations comprising: controlling the display so as to display a screen showing a plurality of display areas corresponding to the plurality of holding regions respectively, the display areas being selectable, obtaining reagent name information which represents the name of a reagent contained in a first reagent container, based on the identification information of the first container read by the reader; selectively displaying the obtained reagent name information on a first display area corresponding to a first holding region which holds the first reagent container, wherein the display includes a second display area corresponding to an unpopulated holding region and wherein reagent name information is not displayed in the second display area; receiving, through the input device, a selection of the second display area from the plurality of display areas; and controlling the holding section so as to move the second holding region to a container-addition position at which the a second reagent container is added to the holding section.
