Abstract

There is provided a test method for analysing a body fluid in which a test tape is used in a test device in order 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. In order 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.
