ABSTRACT OF THE DISCLOSURE A testing composition provided in test-strip form, which comprises a predetermined amount of a coloured indicator on a solid, inert support, the indicator being responsive to the material being tested in such a manner it loses its colour in a direct proportion to the amount of material present. The testing composition may be provided with a semi-permeable membrane to prevent the deposition of suspended particles on the composition. Also provided is a method of determining the minimum or maximum level of a material, for instance uric acid, in fluids using the test- ing composition and comparing it with a comparator strip.
