Abstract: A method for detecting at least one analyte in a body fluid is disclosed comprising performing an optical measurement, wherein at least one test chemical is contacts the body fluid. The test chemical is an optical test chemical adapted to perform at least one detection reaction, wherein at least one optically detectable property is changed due to the detection reaction to provide at least one optical measurement value. At least one impedance measurement is generated wherein at least one alternating electrical signal is applied to the body fluid via the impedance measurement electrodes and at least one answer signal is recorded, and at least one impedance measurement value is generated. At least one evaluation step is performed wherein at least one evaluation algorithm is used, and the optical measurement value and the impedance measurement value are used for determining a concentration of the analyte in the body fluid.

Abstract: A test element for electrochemically detecting at least one analyte in a bodily fluid is disclosed. The test element comprises at least one first electrode and at least one second electrode. The first electrode is designed as a working electrode and the second electrode is designed as a counter electrode. The test element comprises at least one capillary capable of receiving a sample of the body fluid. The first electrode and the second electrode are arranged on opposing sides of the capillary. The first electrode and the second electrode are arranged such that during a capillary filling the first electrode and the second electrode are wetted simultaneously and at an equal rate.
