Abstract

A testing assembly for lateral flow assay comprising a liquid sample receiving unit arranged on a support structure defining a plane and configured to receive a liquid sample via the liquid sample receiving interface, at least one testing strip having, in a planar state, a testing strip center line length (L) in a longitudinal direction, a testing strip width in a width direction and a testing strip thickness, and comprising a capillary wick that includes a test portion that comprises a reacting material configured to react in a predetermined manner to a pre-specified analyte, wherein the width direction of the testing strip extends at an angle smaller than 90° with respect to a normal of the plane, and wherein the testing strip is curved, resulting in an effective extension being shorter than the testing strip center line length in the planar state.
