Problems solved by technology

[0014] Such a contact with ruthenium dioxide may be disadvantageous, since the application of ruthenium dioxide may be complicated and expensive
In particular, galvanic coating may not be possible and thus it may be expensive and uneconomical to manufacture ruthenium dioxide contacts

Embodiment Construction

[0072] figure 1 A test element analysis system 110 including an evaluation device 112 is shown. The evaluation device 112 has a test element holder 114 for positioning a test element 116 containing a sample 118 . The test element holder 114 can be configured to position the test element 116 in figure 1 in the measurement position shown in . The test element 116 can be fixed in the measuring position by suitable means, for example by a spring element 120 . To carry out the measurement, a sample liquid can be brought into the measurement zone 122 of the test element 116 . In the illustrated embodiment, this is accomplished by applying a liquid droplet to a sample application zone 124 provided at the end of the test element 116 and transporting it from that location to the measurement zone via a transport zone 126 (eg capillary channel). 122 to happen. A reagent layer 128 may be located in the measurement zone 122, which reagent layer 128 may be dissolved by the sample liqui...

Abstract

A test element analysis system (110) for an analytical examination of a sample (118), in particular of a body fluid, is disclosed. The test element analysis system (118) comprises an evaluation device(112) with a test element holder (114) for positioning a test element (116) containing the sample (118) and a measuring device (134) for measuring a change in a measuring zone (122) of the test element (116), the change being characteristic for an analyte. The test element holder (114) contains contact elements (132) with contact surfaces (133) which allow an electrical contact between contact surfaces (117) of the test element (116) and the contact surfaces (132) of the test element holder (114). The contact surfaces (133) of the contact elements (132) of the test element holder (114) are provided with an electrically conductive surface (145) containing metallic ruthenium (146).

Description

technical field [0001] The invention relates to a test element analysis system for the analytical examination of samples and in particular human or animal body fluids and a method for producing the test element analysis system. Background technique [0002] Test element analysis systems are often used inter alia in medical diagnostics for analyzing bodily fluids such as blood or urine. The sample to be inspected is first applied to the test element. Here, the process steps required for the detection of an analyte are generally chemical, biochemical, biological or immunological detection reactions or physical interactions which lead to characteristic and measurable changes of the test element, especially in the region of the measurement zone of the test element. In order to determine this characteristic change, the test element is inserted into an evaluation device, which determines the characteristic change of the test element and provides this characteristic change in the ...
