<p>Independent reagent matrix zones are created in hydrophobic open celled natural or synthetic material by heating the open celled material along parallel lines at right angles to the length of a reagent test device so as to seal the material at predetermined intervals and thereby form separate reagent matrix areas on the same reagent test device. This technique results in a reagent test device which eliminates the runover problem which has caused cross contamination between reagent areas and resulted in the failure of reagent test devices to perform properly.</p> |
