1. A method for semi-quantitative or quantitative analysis of a plurality of assays, wherein the method comprises: assigning at least one unique barcode coded text segment on a first portion of at least one of a test strip or a cassette of at least one of the plurality of assays, the at least one of the test strip or the cassette further comprising a second portion distinct from the first portion, the second portion comprising at least a response zone and a control zone; acquiring an image of at least one of the test strip and the cassette, the image comprising the at least one unique barcode coded text segment and at least one test result line in the response zone, the at least one test result line being generated by the at least one of the plurality of assays; identifying the at least one unique barcode coded text segment in the acquired image and using the identified barcode coded text segment as an optical calibration entity; using the optical calibration entity and geometric information from a database to detect a search area of at least one control line in the control zone; and using an identified position of the at least one control line and the geometric information from the database to detect a search area for the at least one test result line.
