Abstract
Disclosed, in one aspect, is an assay result reading device for reading the result of an assay performed using a test strip, the device comprising: a light source or sources, said light source/s emitting light incident upon at least two, spatially separated zones of the test strip; and a photodetector which detects light emanating from each of the two said zones; in a further aspect is disclosed an assay result reading device for reading the result of an assay performed using a test strip, the device comprising: at least one light source incident upon a zone of the test strip; and at least two photodetectors both of which are able to detect some of the light emanating from the zone of the test strip illuminated by the light source.

17. A method of determining the result of an assay performed using a test strip, the method comprising:
-
positioning the test strip in relation to an assay result reader, the reader comprising a housing enclosing at least one light source and a photodetector; and
measuring a light level received by the photodetector;
wherein the test strip is so positioned that the at least one light source emits light incident on at least two spatially separated zones of the test strip, and so that light emanating from at least one of the zones is incident on the photodetector. - View Dependent Claims (18, 19)

20. A method of determining the result of an assay performed using a test strip, the method comprising:
-
positioning the test strip in relation to an assay result reader, the reader comprising a housing enclosing at least one light source and at least two photodetectors; and
measuring a light level received by the photodetector;
wherein the test strip is so positioned that the at least one light source emits light incident on the at least one zone of the test strip, and so that light emanating from the at least one zone is incident on each photodetector.
