Testing assembly and testing device for lateral flow assay

A testing assembly for lateral flow assay, the testing assembly comprising:

• a liquid sample receiving interface arranged on a support structure defining a plane, the liquid sample receiving interface being configured to receive a liquid sample;
• at least one testing strip fluidly connected to the liquid sample receiving interface, the testing strip having, in a planar state, a testing strip center line length, a testing strip width and a testing strip thickness that is shorter than the testing strip center line length and the testing strip width, the testing strip comprising:
• a capillary wick fluidly connected to the liquid sample receiving interface and including at least one test portion, the test portion comprising at least one respective reacting material configured to react in a predetermined manner to at least one respective pre-specified analyte;
• wherein a width direction of the testing strip extends at an angle smaller than 90° with respect to a normal of the plane defined by the support structure;
• and
• wherein the testing strip is curved, resulting in a shortest distance between two opposite longitudinal ends of a testing strip center line being shorter than the testing strip center line length in the planar state.
