A method for producing a detection / test tape includes depositing a material onto a surface of at least one first substrate to form a plurality of element structures. Electrodes are deposited on a surface of each of the plurality of element structures, and the element structures are bonded to a second substrate, where the second substrate is conductive or has a conductive layer, and the second substrate is carried on a carrier plate. The at least one first substrate is removed from the element structures and second side electrodes are deposited on a second surface of each of the plurality of element structures. An insulative material is inserted around the element structures to electrically isolate the two substrates used to bond the element structures. A second side of the element structures is then bonded to another substrate, where the other substrate is conductive or has a conductive layer. Thereafter, the carrier plate carrying the second substrate is removed.

There is provided a test method for analyzing a body fluid in which a test tape is used in a test device to successively provide analytical test fields stored on the test tape, wherein body fluid is applied by a user to the test field provided at a time and the said test field is photometrically scanned using a measuring unit of the device to record measurement signals. To increase the measurement reliability, it is proposed that a control value is determined from a time-dependent and / or wavelength-dependent change in the measurement signals and that the measurement signals are processed as valid or discarded as erroneous depending on the control value.

The present invention provides a portable blood sugar measuring device comprising a tape unit for winding a test tape forward in sections, a detection unit for detecting measured values on the sections of tape to which body fluid has been applied, and a housing to hold the tape unit and detection unit. The tape unit and / or the detection unit can be deflected relative to the housing (10) from an operating position against a flexible restoring element (18) when subjected to a shock load.
