A test element support comprises a heating element for heating a test element for analytical examination of a sample. The heating element comprises a substrate, which is made of at least one substrate material. The substrate comprises at least one active area configured for being heated and at least one non-active area outside the active area. The active and the non-active areas are separated by at least one thermal insulation element. The thermal insulation element has a lower thermal conductivity than the substrate material. The thermal insulation element is fully or partially embedded into the substrate. The test element support further comprises at least one heater. The heater comprises at least one heater substrate and the heater substrate is attached to the substrate, wherein the heater substrate is attached to a back face of the substrate. The back face opposes a front face of the substrate contacting the test element.

Test element support

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.

Test element for electrochemically detecting at least one analyte

A medical instrument and method thereof for performing a measurement on a biological sample using a test strip are disclosed. The medical instrument may comprise: an analytical unit for analyzing the test strip, wherein the analytical unit comprises a test strip mount which receives the test strip to perform the measurement; a test strip port which receives the test strip, wherein the test strip port is aligned with the test strip mount along an insertion direction; and a shutter movable between open and closed positions, the shutter comprises a test strip opening, wherein the test strip opening is aligned with the test strip port and the test strip mount when the shutter is in the open position, wherein the shutter comprises a shutter mechanism that rotates the shutter parallel to the insertion direction about a rotational axis to move the shutter between the open position and the closed position.
