Abstract

A test carrier for the analysis of fluids has a test field which is held in a frame and a test application surface for the application of a sample fluid. Sometimes called an "analysis chip", such devices are suitable for accommodating a test layer pack which has a plurality of layers lying loosely on one another. These devices are thin and allow for low cost manufacturing and simple and efficient handling, and has a base body of a plastic material, with a trough-shaped depression for accommodating the test field therein. A retaining net of a plastic material spans above the depression and the test field.
