1. A test for the analysis of one or more analytes in a fluid test sample, the test comprising:

  • a carrier of an absorbent material;

    said carrier exhibiting light reflectance within a first predetermined spectral range;

    a plurality of test fields on the surface of the carrier;

    said test fields including a plurality of test field materials reactive with the one or more analytes and exhibiting light reflectances within a second predetermined spectral range;

    said first and second predetermined spectral ranges being distinguishable from one another;

    said plurality of test fields being disposed in spaced relation to one another on the carrier, wherein gaps between the test fields exhibit light reflectance within said first predetermined spectral range;

    said gaps and said test fields having relative sizes which are optically discernable;

    said relative sizes forming a coded sequence that correlates to information relating to the test.
