1. A device for receiving a digital reader and a lateral flow assay (LFA) cartridge, the device comprising a body and a base plate,
the body comprising:
a wall enclosing a space, the wall comprising a top portion and a bottom portion;
a frame coupled to the top portion of the wall, the frame configured to receive the digital reader;
a mating structure defined by the bottom portion of the wall, wherein the mating structure is configured to removably couple to a base plate;
the base plate comprising a first surface and a second surface defining a space therebetween, the space comprising,
a first LFA cartridge receiving portion,
wherein the first LFA cartridge receiving portion comprises a substantially planar first support surface that receives and holds a LFA cartridge in a substantially fixed position,
wherein the first support surface is at a first fixed orientation relative to a planar space defined by the frame, and
wherein the mating structure and at least a portion of the base plate have a shape having a line of symmetry such that the mating structure and the base plate are couplable in at least two orientations by rotation of one of the mating structure and the base plate.
