ABSTRACT:
Test carrier analysis system for the analytical determination of a component of a sample fluid, in particular of a body fluid. The system comprises test carriers (1) with a color formation layer (5) which is attached movably to the test carrier. The color formation layer is in the initial state of the test carrier not in fluid contact with a fluid reservoir layer (4) likewise attached to the test carrier, but can be pressed against the latter by external manipulation. The system also incorporates an evaluation apparatus with a pressure element (10a) for the pressing of the color formation layer (5) and a control unit (25) for controlling the apparatus functions. In order to improve the analytical determination as regards simplicity of handling and accuracy of the analysis, the reference measurement and the sample measurement are under the control of the control unit (25) carried out in turn on the color formation layer serving as reference surface by means of the same optical unit (1), after the color formation layer has been pressed against the fluid reservoir layer (4) by means of the pressure element (10a).
