1. A diagnostic test carrier for the determination of an analyte in a liquid sample, comprisinga supporting layer;

  • a detection layer arranged on the supporting layer, said detection layer having reagents incorporated therewith for the detection of an analyte in a liquid sample; and

    a network covering the detection layer, wherein the network is larger than the detection layer, the network extends beyond the detection layer, and the network is attached to the supporting layer, such that capillary liquid transport is possible from the detection layer to a part of the network which extends beyond the detection layer;

    wherein the network is a multi-thread knitted fabric having, a thread of a first material located on a side of the fabric facing away from the detection layer, and a thread of a second material located on a side of the fabric facing the detection layer, and wherein the thread of the second material has a surface roughness which is greater than a surface roughness of the thread of the first material.
