  • (a) a recording surface which is capable of being marked by a user of said test;

    (b) an array of recording zones on said recording surface, one recording zone for each of a series of occasions on which a said test is to be performed, and each said recording zone including a series of outcome zones each associated with a possible outcome of said test on a said occasion, whereby a two-dimensional array of outcome zones is provided on said recording surface;

    (c) for each recording zone, at or adjacent said outcome zones, a series of representations of colors or other visual appearances of said test material corresponding to each of the possible outcomes of which one is to be recorded in each said recording zone;

    whereby, in use, when markings are made by a user on a said recording device, one marking for each of a series of tests carried out by the user, and one marking per recording zone at or adjacent the outcome zone associated with that representation of the test outcome which corresponds to the appearance of the test result obtained for recording, said markings yield a graph of the test results made up of said markings.
