Abstract
The invention concerns a method for producing integrated, diagnostic test elements (1) which have a lancing area (2) and a detection area (3). The lancing area is used to generate an opening in the skin and the detection area is used to detect an analyte in a body fluid. The selective sterilization sterilizes the lancing area but not the detection area by electron radiation. The method according to the invention comprises the steps of screening the detection area on the test element against electron radiation and subsequently irradiating the test element with electron radiation. The invention additionally concerns a method according to the invention in which the test elements and lancing areas are in a connected arrangement and are brought into the radiation area by moving the entire arrangement. Finally the invention concerns a diagnostic test element which has been produced according to the inventive method.
