Abstract

Test carrier for the analysis of fluids with a frame (2) consisting of at least two parts surrounding a test field opening (6) and with a test field disposed in the test field opening (6). In order to provide such a test carrier with frame with which it is possible to assemble the test field out of several test layers manufactured separately from one another, it is proposed that the test field be designed as a test layer package (7) with test layers (10, 11, 12) resting loosely on one another, the frame (2) comprise two shaped pieces of plastics material, one of which serves as base part (4) and comprises a seat (16) for accommodating the test layers (10, 11, 12), while the other serves as lid part (3) and comprises a bearing surface (17) resting on the topmost layer (10) of the test layer package (7). The lid part (3) and the base part (4) are in addition designed with elastic properties so that the pressure with which the bearing surface (17) presses onto the test layer package (7) is substantially constant in the tolerance range of the thickness of the test field package (7).
