OPTICAL INTERPRETATION OF ASSAY RESULTS

摘要

The inventive concepts disclosed herein are generally directed to the use of a hand-held mobile computing device, such a smartphone or tablet, to interpret the results of a medical assay device. By controlling conditions like image placement and illumination and correcting for imperfect illumination, accurate results can be obtained with hand-held mobile computing device.

主权项

1. A stand for a mobile computing device, comprising
a reading location capable of supporting an assay device having a testing region; a raised platform disposed a distance above the reading location along a line extending from the raised platform to the reading location, the raised platform having a through hole, the through hole capable of being aligned with a camera on the mobile computing device when the mobile computing device is placed on the raised platform; a light source disposed between the reading location and the raised platform, the light source directing light at the assay reading location area substantially along the line, the light source allowing the camera an unobstructed view the testing area of the assay device when the camera of the mobile computing device is aligned with the through hole and when an assay device is placed on the reading location; a first polarized lens disposed between the light source and the assay reading location, wherein substantially all of the light emanating from the light source passes through the first polarized lens, wherein the first polarized lens is polarized in a first direction; a second polarized lens disposed between the camera and the assay reading location, wherein when the camera of the mobile computing device is aligned with the through hole and when an assay device is placed on the reading location, the testing region of the assay device is visible to the camera through the second polarized lens, wherein the second polarized lens is polarized in a second direction that is perpendicular to the first direction; and at least one exterior surface, wherein the combination of the raised platform and the at least one exterior surface prevent substantially all external light from reaching the reading location, wherein external light is lighting emanating from outside of the stand.
