Abstract

A test element analysis system for the analytical investigation of a liquid sample. The test element comprising a carrier film having a first light guide layer having a flat side, a second light guide layer positioned adjacent to the first light guide layer and opposite of the flat side, and a coupling out zone which is part of the flat side of the first light guide layer. A test field is secured to the flat side and is constructed and arranged to receive a liquid sample. The test field comprises a reagent system having a soluble reagent capable of causing an optically measurable change upon reaction with an analyte of the liquid sample, and a detection zone in optical contact with the coupling out zone.
