Abstract
The invention concerns a diagnostic test carrier (1) containing a supporting layer (2) with a detection layer (3) arranged thereon containing reagents required for the determination of an analyte in a liquid sample and an inert layer (4) covering the detection layer (3) wherein the inert layer (4) is arranged at such a distance (5) from the detection layer to enable a capillary active liquid transport between the detection layer and inert layer (3,4), characterized in that the inert layer (4) extends beyond the detection layer and wherein the area (10) that extends beyond the detection layer is attached to the supporting layer (2) in such a way that a continuous capillary active liquid transport between the inert layer and detection layer (4,3) and between the inert layer and supporting layer (4,2) is possible and in addition the inert layer (4) contains several holes (7) in the area of the detection layer (3) through which the sample to be examined and the components contained therein can be applied to the detection layer (3) as well as its use for the determination of an analyte in a liquid.
