PROBLEM TO BE SOLVED: To achieve an automatic analyzer capable of detecting measurement value abnormality caused by reaction process abnormality due to bubbles or a foreign substance without complicating processing and functions of the analyzer.SOLUTION: Measurement value abnormality check is started to check whether or not concentration operation results based on optical quantity data from a plurality of pair detectors are included within a fixed quantity range (steps a, b). When the concentration operation results are within the fixed quantity range, an average value of concentration operation results by a target detector is calculated, and when the concentration operation results are out of the fixed quantity range, a flag is given and an average value of concentration operation results in the target detector is calculated (steps c, d). A variation width predetermined value in the average value of the concentration operation results is accessed, a variation width of the concentration operation results in the plurality of target detectors is calculated and whether the variation width is included within a predetermined range or not is determined (steps e, f, g). When the variation width is within the predetermined range, the concentration operation results are outputted to a display, and when the variation width is out of the predetermined range, a re-inspection request is displayed and a measurement value abnormality alarm is added (steps h, i, j). |
