Abstract
The present invention provides assay devices and methods for detecting the presence of an analyte in a sample. Devices according to the invention include a reagent zone, one or more capture zones and a detection zone. Capture zones can reduce the quantity of labelled conjugate that reaches the detection zone in the presence of a negative marker in the sample and/or in the absence of a positive marker in the sample, facilitating high sensitivity and improved specificity testing.
