The present invention relates to testing biological or industrial samples. Disclosed by preferred embodiments is an electronic assay test reader for reading a lateral flow test strip having a development area comprising a test background region and at least one test result line, the electronic lateral flow assay test reader comprising: a cassette for retaining the test strip and a carrier adapted to removably retain the cassette therein; at least one illumination LED operably associated with one or a combination of the cassette and the carrier for illuminating the test strip, and; a light guide comprising a window structure of one or a combination of the cassette and the carrier to direct light emitted or reflected from a selected portion of the development area of the test strip to a sensor wherein the proportion of the at least one test result line relative to the proportion of test background region in the selected portion of the development area of the test strip is maximised.
