Abstract

An indicator element (110), and methods for the making of such an indicator element, for providing a visual indication of the presence or absence of a substance in a fluid, comprising a carrier and a reagent carried by the carrier, the reagent being distributed over the surface and/or within the body of the carrier in such a way that a visually discernible change (150,160,170) to the indicator element occurs upon reaction of the reagent with one or more target substance.
