Measurement system for an analyte determination and a method

A measurement system for analyte determination, the system comprising:

• an analysis unit programmed to determine an analyte measured value for a body fluid specimen applied,
• a fingerprint sensor unit programmed to detect first fingerprint sensor signals and second fingerprint sensor signals for one or various users, wherein the first fingerprint sensor signals are obtained from one finger and the second fingerprint sensor signals are obtained from another finger,
• a memory unit to store analyte measured values as well as first and second fingerprint sensor signals,
• display, and
• a control unit connected to the analysis unit and to the fingerprint sensor unit for data transmission, wherein the control unit is programmed to perform a user identification using first fingerprint sensor signals and to enable a determination of an analyte measured value on successful user identification using the analysis unit for an identified user by comparing detected first fingerprint sensor signals to first fingerprint signals stored in the memory unit and recognizing the detected first fingerprint sensor signals as one stored in the memory unit,
• the control unit is further programmed to perform a supplementary analysis of the first and second fingerprint sensor signals and to provide control signals for user information as a function thereof, wherein the supplementary analysis includes analysis of the detected first and second fingerprint sensor signals to determine scarring of the tissue of the finger and advise via the display a user to insert a different finger for body fluid specimen analyte measurement.
