Abstract

An analytical test element for determining an analyte in a body fluid comprises a detection area in which the analyte is detected and an application site at which the body fluid can be applied to the test element. The application site is spaced apart from the detection area, wherein at least some of the body fluid applied to the application site moves from the application site to the detection area. The test element also comprises a contamination area which at least partially adjoins the application site, wherein an adhesive substance is applied to at least part of the contamination area of the test element. The adhesive substance adheres to the contamination area of the test element and is able to interact with an excess amount of applied body fluid such that at least some of the body fluid adheres to the test element and thereby an excess amount of body fluid remains in the contamination area. An additional embodiment provides for test elements which, after use, can be stored in a storage container. Another embodiment provides for the production of the test elements.
