Abstract

Test carrier for the analysis of fluids with a test field (7) held in a frame (2), in which the frame (2) comprises a top part (3) and a base part (4) and at least the top part (3) comprises a test field opening (6) through which a sample fluid can be applied to the surface (7a) of the test field. Simplified handling and improved analytical reliability are achieved by the fact that the base part (4) comprises a seat (16) for the test field (7) which is surrounded by positioning elements (15) which are higher than the test field (7). The test field opening (6) is greater than the test field (7), so that the rim (18) of the test field is visible. The top part (3) comprises pressure tongues resting on the surface (7a) of the test field (7) and projecting into the test field opening (7).
