The test element for making a puncture wound in a body part, for receiving a body fluid sample from the body part and for analyzing using a reagent system, whose reaction guides with analytes contained in the body fluid for a modification of one of the characteristic measured parameters of the test element optically measurable for the desired analytical results, comprises a lancing element (3) and a testing field (5), which contains a part of the reagent system. The lancing element has a nib at one end of the lancing element for making the wound in the body part, and a capillary structure. The test element for making a puncture wound in a body part, for receiving a body fluid sample from the body part and for analyzing using a reagent system, whose reaction guides with analytes contained in the body fluid for a modification of one of the characteristic measured parameters of the test element optically measurable for the desired analytical results, comprises a lancing element (3) and a testing field (5), which contains a part of the reagent system. The lancing element has a nib at one end of the lancing element for making the wound in the body part, and a capillary structure that is designed, so that the body fluid penetrates into the capillary structure after inserting the nib of the lancing element into the skin. The lancing element and the testing field are positionable relative to each other in a liquid transfer position, so that the testing field fluidically contacts to a part of the capillary structure of the lancing element. The body fluid penetrating into the capillary structure is transferred to the testing field. The testing field comprises a transparent supporting layer (100) and a testing layer introduced on the supporting layer by coating, where the side of the testing layer turned away from the supporting layer forms the fluid entry side, which is turned towards the capillary structure in the liquid transfer position and directly adjoins to the capillar
