Test element and method of use for analyzing body fluids
First Claim
1. An analytical test element for determining presence or concentration of an analyte in a body fluid, comprising:
- an application site adapted to receive a body fluid sample;
a detection area spaced from the application site and configured for analyzing the body fluid sample;
a transport element disposed between the application site and the detection area, the transport element being configured to transport the body fluid sample from the application site to the detection area; and
a contamination area at least partially adjoining and surrounding the application site, the contamination area comprising an adhesive exposed for contact by the body fluid sample and adapted to adhere a dried portion of the body fluid sample to the analytical test element.

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.
