Abstract: A biochemical analyzer has a control section which outputs the results of analysis of measurement values from a reactant measured by a multi-wavelength photometer to a host device through a communication section. The control section causes both analyte identification information for identifying the analyte instructed to be retested through the communication section from the host device and analyte receptacle positional information indicative of the position of a sample receptacle receiving the analyte instructed to be retested from the host device on a sample turntable to be displayed on a display unit.

Abstract: An operator who operates an automatic analyzer can easily recognize a timing of adding a reagent to a specimen. reagent is added to a specimen in a reaction container to cause the reagent and the specimen to react with each other, an optical property of the specimen in the reaction container is measured, and a display screen for measurement data is created. A display screen 100 for a measurement-data graph indicating a change over time in the measurement data (or a measurement-data list indicating a list of measurement data) is created as a display screen for the measurement data. In this display screen 100, a display “x” or “y” indicating an addition timing of the reagent in the reaction container is added.
