Abstract:
PROBLEM TO BE SOLVED: To monitor whether an analysis region of a test element is positioned in an analysis position in a test element receptacle relative to the analysis unit. SOLUTION: The monitoring includes a step of irradiating the analysis region with light from at least one light source, a step of detecting light scattered or reflected at the analysis region by a detector for obtaining detection signals, and a step of evaluating the detection signals by an evaluation unit. In this case, delimitation of a light-transmissive region arranged between the test element and the detector is effected by a delimiting element having a light-opaque region.

Abstract:
The method involves irradiating an analysis region (2) with light from a monitoring light source, and detecting responsive detection signals by a detector (12). A light-transmissive region (14) arranged between a test element and a detector is delimited by a delimiting element (15) comprising a light-opaque region. The detection signals are evaluated using an evaluation unit, and the detection signals are compared with a predetermined limit value corresponding to a correct analysis position with respect to Z direction. An independent claim is also included for an analysis system comprising a monitoring unit.
