摘要： Disclosed is an assay result reading apparatus for use with an assay in which a detectable substance tends to accumulate within a detection zone of the assay, the reading apparatus comprising: a housing or baffle, having a window therein; a light source which emits light through the window so as to illuminate the detection zone of the assay; and a light detector to detect the amount of light reflected and/or transmitted by the detection zone, which amount is at least partly dependent on the amount of detectable substance accumulated in the detection zone; wherein the shape of the window is adapted to render the reading apparatus less sensitive, preferably insensitive, to minor mis-positioning of the detection zone relative to one or more of the window, the light source and the light detector.

摘要： Disclosed is an assay device comprising liquid transport means adapted to take up a liquid sample and conduct the liquid to an analyte detection region operable to provide a test signal indicative of the presence and/or amount of an analyte in the liquid sample; the assay device further comprising a sample presence signal generation means, which is not generated by means of an immunoreaction. This sample presence signal generation means can comprise a colored portion, which is overlaid by a material (e.g. nitrocellulose) that is opaque, when dry, and translucent or transparent, when wet, to allow the colored portion to become visible to the user. In another embodiment the signal generation means comprises a color changing material which under-goes a change in its visible properties upon wetting (e.g. pH indication). A third embodiment uses a mobilizable detectable which, when wetted by the sample, is carried along resulting in a streaked line parallel with the flow direction.
