ABSTRACT An apparatus for the evaluation of a flat test carrier for the analytical determination of com- ponents of a body fluid, has a measurement unit and a positioning means which positions and firmly holds a test carrier in a measurement position so that its test field is present in a definite position with regard to the measurement unit; for the evaluation of test carriers with a covering layer fixed in the manner of a flap on one edge of the test carrier, the apparatus includes, an aperture element with a contact surface adapted to press on the covering layer, at least one of the aperture element and the positioning means being mounted and operable in such a manner that the contact surface in the last phase of approaching the covering layer is adapted to make, relative to the test carrier, a tilting movement about a tilting axis which lies in close proximity to the fixing edge of the covering layer; in a different embodiment the positioning means includes at least first and second holding means, the first holding means firmly holding the test carrier close to an insertion end and the second holding means firmly holding the test carrier close to its handling end, a supporting surface on which the test carrier lies at least partly in its measurement position, and the positioning means includes a tensioning element which tensions the test carrier in the measurement position along its longitudinal axis between the first and second holding means; the apparatus of the invention permits simple handling and exactitude of evaluation.
