Abstract

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.
