The present invention provides a test carrier for the analysis of a sample liquid and especially of a body fluid, having a porous test layer (8, 13) which contains a solid component (9, 17), wherein the solid component (9, 17) is coated with a protein which is insoluble in the sample liquid under the test conditions. A process for the production of this test layer is also disclosed, wherein the protein is dissolved in a solvent under conditions under which the solubility of the protein is sufficiently high in order to dissolve a certain minimum amount of the protein, the solid component of the test layer is contracted with the solution and the solubility is reduced to such an extent that the component is coated by the precipitating protein.
