A blood sugar analyzing apparatus has a reaction cell which houses a fixed enzyme membrane sensor and a measuring electrode which receives a blood specimen which causes a chemical reaction between the blood specimen and said fixed enzyme membrane for measuring the blood sugar concentration in the specimen on the basis of a reaction current signal generated in the sensor by the chemical reaction. The analyzing apparatus has a microcomputer for calculating a conversion coefficient used for converting the reaction current into a blood sugar concentration value by introducing a standard solution having a known blood sugar concentration, for storing data representing the value of said conversion coefficient, for calculating a blood sugar concentration value of a test specimen based upon the stored conversion coefficient value and reaction current from the test specimen. A display and printer provide a read-out of the blood sugar concentration value obtained. The microcomputer controls temperature and timing of the measurement process, as well as other control functions.
