A measurement system and method for operating a measurement system is disclosed for an analyte determination. The system includes an analysis unit, which is configured to determine a measured analyte value for a body fluid specimen that is applied, a fingerprint sensor, which is configured to detect fingerprint sensor signals for one or various users, and a control unit, which is connected to the analysis unit and the fingerprint sensor unit for data transmission. The control unit is configured to perform a user identification using the detected fingerprint sensor signals and after successful user identification to enable a determination of a measured analyte value with the analysis unit for an identified user. The control unit is additionally configured to analyze the detected fingerprint sensor signals and optionally additional detected fingerprint sensor signals in addition to the user identification in order to provide control signals for performing additional measurement system functions.
