<p>A test system and method is described for determining under alkaline conditions if a material (eg. uric acid) oxidizable by iodine is present in a fluid in an amount equal to or greater than a predetermined amount, and which includes an indicator, for indicating the presence of iodine, and an iodine generator, for rapidly generating iodine in situ on activation by water, to colour the indicator, the system being applied to a test strip. There is also provided a source of basic anions capable upon activation of neutralizing excess protons remaining after generating-iodine in situ, to permit rapid oxidation of the material oxidizable by iodine without substantially interfering with the rapid generation of the iodine.</p> |
