TEST METHOD AND TEST DEVICE FOR ANALYSING A BODY FLUID

摘要

There is provided a test method for analysing 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.

1. A method of analyzing a body fluid for blood sugar determination in which a test tape in the form of a tape cassette is used in a test device to successively provide a plurality of analytical test fields stored on the test tape by means of tape transport, the method comprising the steps of:
applying the body fluid to the test field at a time; and photometrically scanning over a duration of a measurement interval the test field via a measuring unit of the test device to detect measurement signals for blood sugar determination, wherein a lot control value is determined during a batchwise production of the tape cassette by measuring test fields on a test tape material, the lot control value being stored on a storage medium that is applied to the tape cassette, wherein a test field control value is determined from a dry blank value measurement of an unused first test field prior to applying the body fluid, and wherein usability of the first test field is determined by comparing the test field control value to the lot control value.
