Abstract:
1. An assay device for detection of the presence or absence of an analyte in a sample comprising: (a) a sample receiving membrane which conducts flow of a sample, and in flow contact with, (b) an analyte detection membrane which conducts flow of the sample comprising an interfering agent immobilization zone at a first situs, a conjugate forming membrane comprising a mobile labeling reagent at a labeling situs located upstream of the interfering agent immobilization zone, and an immobile capture reagent at a capture situs, wherein the labeling reagent is capable of forming a complex with an analyte and an interfering agent, the capture reagent is capable of binding an analyte-labeling reagent complex, and the interfering agent immobilization zone includes a reagent associated therewith that is capable of binding an interfering agent in the sample.
