| 摘要 |
Disclosed is an assay device for the determination of analyte in a liquid sample over an extended concentration range comprising a first assay and a second assay, wherein the first assay for an analyte comprises a first flow-path having a sole detection zone capable of immobilising a labelled binding reagent and the second assay for said analyte comprises a second flow-path having a sole detection zone capable of immobilising a labelled binding reagent, wherein the presence of labelled binding reagent at the detection zones provides an indication of the presence and/or extent of analyte in said liquid sample.
