Abstract

Disclosed herein are methods of producing a test element for studying a body fluid sample. In the methods, a detection layer is covered with a polymeric spreading layer and applied to a support. The spreading layer can be produced by being sprayed onto the detection layer such that the spreading layer has a thickness of at most about 20 μm. Also disclosed are test elements produced by the methods, as well as tape cassettes incorporating such test elements.
