Novel elements for the analysis of liquids which contain interferents for an analyte assay are described. Interference is reduced in multizone elements by the presence of an interferent-removing zone between the point of introduction of the liquid and the assay-indicator zone wherein the interferent-removing zone comprises a discontinuous phase within a continuous phase. An interferent-removing material is present in the discontinuous phase and the continuous phase is permeable to the analyte, its products and/or the liquid being analyzed.

In an element for analysis of a liquid containing an analyte wherein an interferent is removed from the assay of the analyte, said element comprising at least two zones wherein at least one zone comprises an interferent-removal zone, and at least one additional zone comprises an assay indicator zone

In an element for analysis of a liquid containing an analyte wherein an interferent is removed from the assay of the analyte, said element comprising at least two zones wherein at least one zone comprises an interferent-removal zone, and at least one additional zone comprises an assay indicator zone, the improvement wherein the zone for interferent-removal comprises a discontinuous liquid phase within a continuous phase wherein the discontinuous liquid phase comprises a material for extracting an interferent to the assay of said analyte and the continuous phase is permeable to said liquid under analysis, the analyte or an interaction product, said interferent-removal zone being located between the assay indicator zone and the point of introduction of the liquid.
