The present invention encompasses a capture membrane comprising a porous filter membrane having a hapten bound directly or indirectly to the membrane wherein complexes formed by specific binding having an anti-hapten bound to a binding member of the specifically binding complex are removed from a solution by the hapten as the solution passes through the membrane. In the preferred embodiment biotin is the hapten and avidin or streptavidin is the anti-hapten.

Novel methods and devices are provided for detecting analytes, where the sample is placed upstream from a reagent which is a component of a signal-producing system. The detection zone is provided upstream from the sample, where the amount of reagent which becomes bound at two sites is determined and the two values used for an accurate determination of an analyte.
