ABSTRACT:
The invention concerns a diagnostic test carrier (1) containing a supporting layer (2) with a detection layer (3) arranged thereon containing the reagents required to determine an analyte in a liquid sample and a network (4) covering the detection layer (3) which is larger than the detection layer (3) and which is attached to the supporting layer (2), wherein the network (4) is a plied knitted fabric the threads of which are highly roughened on the side facing the detection layer (3) whereas the threads on the side of the knitted fabric which face away from the detection layer (3) are relatively smooth as well as the use of such a test carrier to determine an analyte in a liquid and the use of such a knitted fabric as a layer spreading liquid in a diagnostic test carrier. Moreover the invention concerns a method for the determination of an analyte in a liquid sample with the aid of a test carrier according to the invention.
