1. Test carrier assembly for the analytical determination of a component of a body fluid, comprising a base layer and at least two planar test layers which, in the initial state of the assembly, before the determination is carried out, are separate from one another but can be contacted by external manipulation, wherein a first test layer and a second test layer are arranged on the base layer essentially next to one another but separated by a gap, and a capillary-active material contact element is movable between two positions, an initial position and a contacting position, with the initial position being located so that the contact element does not contact at least one of the test layers, and the contacting position being such that upon the application of external pressure the contact element assumes the contacting position to bridge the gap and contacts both test layers to permit liquid exchange thereinbetween.
