Abstract: Computing systems, computer-readable media and methods are disclosed. In the computing system, an image capture device captures an image of a protein array including spots of predetermined proteins, wherein some of the spots have bound to a biological material having individual-specific antibodies to form immune complexes and some of the immune complexes have interacted with a detection agent to generate a visible image therefrom. The computing system may be operably coupled to the image capture device and processes the captured image of the protein array to determine control locations of a plurality of control spots in known locations on the protein array. The computing system also extrapolates expected locations of all other spots on the protein array from the control locations.
