Assay device with shared zones
First Claim
1. An assay device for determining the presence and/or extent of one or more analyses in a liquid sample comprising:
- a) a first and second test strips each comprising a flow-path, and each having a detection zone for immobilizing a labeled binding reagent, wherein detection of a labeled binding reagent at one or both detection zones is indicative of the presence and/or extent of one or more analytes;
b) a common sample application zone which fluidically connects the first and second test strips;
c) a shared reference zone;
d) one or more light sources to illuminate the detection zones and the reference zone;
e) one or more photodetectors to detect light from the detection zones and the reference zone, which photodetector generates a signal, the magnitude of which signal is related to the amount of light detected; and
f) signal processing means for processing signals from the photodetector.

Abstract
Disclosed is an assay device for determining the presence and/or extent of one or more analytes in liquid sample containing a) first and second assays each comprising a flow-path having a detection zone for immobilising a labelled binding reagent, wherein detection of a labelled binding reagent at one or both detection zones is indicative of the presence and/or extent of one or more analytes; b) a shared reference zone; c) one or more light sources to illuminate the detection zones and the reference zone; d) one or more photodetectors to detect light from the detection zones and the reference zone, 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.
