Abstract: PURPOSE:To make the operability of diagnosis excellent and to enable automatic takeout of the result of data by providing a glucose analyzing element 1 and a glycohemoglobin analyzing element. CONSTITUTION:Whole blood is injected from a sample injecting element 1 and the concentration of glucose is measured in a glucose analyzing element 2, while glycohemoglobin AIC or a stable type AIC is measured in a glycohemoglobin analyzing element 3. An arithmetic element 4 plots a measured value of the glucose concentration and a measured value of AIC or the stable type AIC on a reference graph for diagnosis in a display element 5. Calculation and storage of the concentration of glucose are conducted by the analyzing element 2, while they can be conducted by the arithmetic element 4. Next, the percentage of AIC is calculated from a fractional component obtained in the analyzing element 3. Since the concentration of glucose and the percentage of AIC can not be obtained simultaneously, on the occasion, the percentage of AIC is held in storage. Lastly, a pair of the measured values of the stored concentration of glucose and the percentage of AIC are plotted on the reference graph for diagnosis prepared first.
