Abstract

The invention concerns an analytical system and a method for determining an analyte which ensures an exact determination by correcting the measured values based on sample- and analyte-independent light intensity changes. The invention takes into account light intensity changes which are based on changes of measurement conditions in the apparatus. The invention is particularly suitable for use in analytical systems for glucose determination in which light-conducting test elements are used.
