Abstract

A diagnostic test tape for liquid samples is provided comprising a flexible transport tape and a plurality of test fields applied to the transport tape that are distributed in the longitudinal direction of the tape, where said test fields comprise a detection layer and a spreading net spanning the detection layer for a planar uptake of liquid sample, wherein the spreading net is formed from a lattice-like fabric comprising fabric threads that cross at right angles. In order to prevent the fabric from arching up under tape tension it is proposed that the fabric is oriented obliquely to the transport tape such that all fabric threads run obliquely to the longitudinal direction of the tape.
