Disclosed is an assay device (20) for determining the presence and/or extent of one or more analytes in liquid sample comprising:
a) first (22) and second (23) assays each comprising a flow-path having a detection zone (24,26) for immobilising a labelled binding reagent, wherein detection of a labelled binding reagent at one or both detection zones (24,26) is indicative of the presence and/or extent of one or more analytes;
b) a shared reference zone (27) and/or control zone (25);
c) one or more light sources to illuminate the detection zones (24,26) and the reference zone (27);
d) one or more photodetectors to detect light from the detection zones (24,26) and the reference zone (27), which photodetector/s generate a signal, the magnitude of which signal is related to the amount of light detected; and
e) signal processing means for processing signals from the photodetector/s. |
