Abstract

The invention relates to a method for monitoring an arrangement for determining a concentration of an analyte in a body fluid. The determination of the concentration of the analyte by means of the arrangement involves a procedure in which the analyte from the body fluid passes through an interface and is transported in a stream of liquid into a flowmeter chamber, in which a measurement is carried out to determine the concentration of the analyte. The evaluation of the measurement takes place in a signal processor. The monitoring of the arrangement comprises the following steps: measurement of measured values of at least two correlated system parameters of the arrangement by means of a sensor system, and comparison of the measured values with limit values stored for each of the system parameters in a storage unit, to obtain a combination of at least two comparison results.
