A hydratable or hydrated gel medium for use in bioassay of a test substance contains fixed in a localized zone a reagent for the test substance. Assays are conducted rapidly by diffusing the test substance followed by an indicator substance also reactive with the reagent into the zone and measuring a change in characteristics within the zone caused by the reaction of the indicator substance.
