Abstract
Non-instrumented assays are providing employing a flow-path with a moveable sample receiving pad, which moves from a sample receiving site to a bridging site between a transport element and a measurement region. A reagent transport solution is employed which comprises enzymes capable of reacting with the analyte to produce hydrogen peroxide, where horseradish peroxidase may catalyze a reaction resulting in the formation of a detectable boundary in the measurement region. The distance of the boundary is indicative of the amount of analyte in a sample.
