1. A background device for an assay test strip, the background device comprising:
a test strip portion sized and shaped to guide placement, on the background device, of a lateral flow assay test strip;
a background portion at least partially surrounding the test strip portion;
a plurality of line detection fiducials disposed on the background portion, each of the plurality of line detection fiducials having a color that is different than a color of a surrounding area of the background portion and a width associated with an expected width of a line on the lateral flow assay test strip; and
one or more additional fiducials disposed on the background portion for evaluation of a modulation transfer function of an image capture device.
