The invention concerns an analytical test element containing an absorbent material with a sample application and detection zone and a blister filled with liquid on a support, wherein the support has a notch within the support surface such that a spike forms there when the support is bent with which the blister can be opened so that liquid escapes and comes into contact with the absorbent material as well as a process for the production of such an analytical test element and a method for determining an analyte by means of such an analytical test element.
