Patent number: 7477404Abstract: The invention relates to embodiments of a method and a system for monitoring the correct positioning of a test element in a test element receptacle of an analysis unit, the test element carrying a sample to be analyzed by the analysis unit. Using a delimiting element, responsive signals resulting from irradiating an analysis region on the test element are effectively prevented from impinging upon a signal detector when the analysis region is in an incorrect position relative to the analysis unit. The delimiting element is provided with a light-opaque region and a light-transmissive region, and the light-opaque region is positioned such that responsive signals impinge upon it rather than the light-transmissive region when the analysis region is in an incorrect position.Type: GrantFiled: August 31, 2007Date of Patent: January 13, 2009Assignee: Roche Diagnostics Operations, Inc.Inventors: Jochen Schulat, Bernd Stenkamp, Guenter Schmelzeisen-Redeker, Wilfried Schmid, Dieter Meinecke, Kai Dickopf, Gertrud Albrecht, Andreas Menke, Bernhard Kern, Wolfgang Schwoebel, Stefan Kalveram
