Problems solved by technology
[0008] Another disadvantage of the known methods is that many known application methods are complex and error-prone with regard to the working and auxiliary substances used for labeling
For example, pigments or inks for marking can be applied by means of printing methods, however this method itself is error-prone in many cases
[0009] Another disadvantage is that the working and auxiliary substances usually applied for marking in the prior art are in many cases applied in liquid form, which requires a drying time after application
The drying time of these markings in many cases limits the manufacturing speed of the production process, thereby increasing production costs considerably

Embodiment Construction
[0143] figure 1 An exemplary embodiment of a production device 110 is represented for producing a test element for detecting at least one analyte in a sample. According to the production state or stage these test elements occupy in the production device 110, or according to the configuration of these test elements, in figure 1 The middle test elements are indicated by reference numerals 112 , 114 and 116 .
[0144] figure 1 The individual elements of the production apparatus 110 in are shown in a symbolic arrangement only. Shown is a continuous production process in which test elements are initially produced as strips 116 on endless belt 118 . For example, the endless belt 118 may be a paper belt, especially a multi-layer coated paper belt. Other support materials may also be used as alternative or additional options, such as plastic tapes, ceramic tapes, composite materials, and similar support materials. For example polyethylene sheets, PET sheets or another sheet can b...

Abstract
The method involves providing a test element e.g. tape-like test element (112), partially with error marking, which contains information of defectiveness of the test elements comprising radiation material. The test elements are charged with a radiation (156), which is arranged to cause a marking in the form of an optically detectable change e.g. florescence change, in the radiation material. A light source (144) e.g. LED, is used for producing the radiation, which comprises an ultraviolet radiation at a wavelength range of 350 nanometers to 380 nanometers. Independent claims are also included for the following: (1) a method for manufacturing a test element (2) a device for manufacturing a test element comprising a test element marking device (3) an analytical testing device for detection of analytes in a sample, comprising a sampling device.
Description
technical field [0001] The invention relates to a marking method for marking defective test elements and to a production method for producing test elements, which production method relates to the marking method according to the invention. The invention further relates to a marking device, in particular for carrying out the marking method according to the invention, and to a production device for producing test elements, which device comprises a marking device according to the invention. The invention further relates to an analytical test device using a test element produced according to the production method according to the invention. Such marking and production methods, marking and production devices and analytical test instruments are used in particular in chemical analysis and medical technology. For example, analytes such as metabolites in samples, in particular liquid samples such as blood, urine, interstitial fluid or other body fluids, can be tested qualitatively and / ...
