An automatic analyzer is provided which is easier to investigate when some troubles such as data abnormality occur in a sample analysis result as compared with an automatic analyzer according to the related art. The automatic analyzer includes: analysis units that perform analysis and quality control analysis for ensuring quality of the analysis; a storage medium that stores quality control results of the quality control analysis performed by the analysis units; a monitor that displays the quality control results; and a control PC that controls an operation of the analysis units (8, 9, and 16), executes, when an arbitrary result is selected from the quality control results stored in the storage medium, based on the selected quality control result, statistical calculation of the selected result and a quality control result performed in the past, and causes the monitor to display a statistical calculation screen as a statistical calculation result.

An automatic analyzer allows identification of the patient specimen for which the specific reagent and the standard solution have been used, and verification of reliability of the analysis results. A plot mark 1-10 is determined depending on whether or not codes and lots as management information of the reagent, standard solution, and accuracy control sample are the same as those used last time. The plot 1-3 represents the start of using the reagent, and 1-4 the reagent use area. The plot 1-5 represents generation of calibration curve data from the standard solution and 1-6 a standard solution use area. The plot 1-7 represents measurement of the accuracy control sample and 1-8 an accuracy control sample use area from a time point of measuring the accuracy control sample as indicated by the plot 1-7 until the next time point. The measurement information 1-14 is the region for displaying the measurement results.

A method for determining a concentration of a chemical of interest in a recirculating analyte system includes the steps of selecting a first indicator threshold, measuring the flow rate of the recirculating analyte system, controllably adding a known amount of reagent to the recirculating analyte system at an known flow rate, repetitively measuring an indicator of the recirculating analyte system downstream from the addition of the reagent, and computing the concentration of the chemical of interest of the recirculating analyte system when the indicator measurement crosses the indicator threshold.
