Abstract
Conductimetric assay devices that have both low end and high end sensitivity are described. The geometric shape and/or arrangement of the capture zones make it possible for the assay devices to have both low end and high end sensitivity. Also described is a conductimetric assay device having a pre-capture zone to capture unbound analyte. The assay device overcomes the problem of flooding by the analyte.
