Abstract:
1. A fluidic assay device for assaying at least one property of a liquid sample, the device comprising: (i) a liquid sample application region; (ii) at least one test flow path in liquid flow communication with the sample application region; (iii) a reference flow path in liquid flow communication with the sample application region; and (iv) a junction region, at which the test flow path and the reference flow path contact one another, the junction region comprising an outlet, conduit, chamber or other portion which permits the onward flow of liquid; wherein one or more vents are provided downstream of the junction region in at least one test flow path and the reference flow path, so that when the liquid reaches the junction region it creates an air lock or gas lock upstream of the vent, which prevents the venting of gas from the other flow path, thereby creating a blocked flow path.
