Abstract
A portable rapid diagnostic test reader system includes a mobile phone having a camera and one or more processors contained within the mobile phone and a modular housing configured to mount to the mobile phone. The modular housing including a receptacle configured to receive a sample tray holding a rapid diagnostic test. At least one illumination source is disposed in the modular housing and located on one side of the rapid diagnostic test. An optical demagnifier is disposed in the modular housing interposed between the rapid diagnostic test and the mobile phone camera.
Claims24
A portable rapid diagnostic test reader system comprising:
- a mobile phone having a camera and one or more processors contained within the mobile phone, the mobile phone containing imaging software thereon executable by the one or more processors;
- a modular housing configured to mount to the mobile phone, the modular housing including a receptacle configured to receive a rapid diagnostic test or a sample tray holding a rapid diagnostic test, the rapid diagnostic test comprising a test location and a control location;
- at least one illumination source disposed in the modular housing and located on one side of the rapid diagnostic test;
- an optical demagnifier disposed in the modular housing, the optical demagnifier demagnifying the image of the rapid diagnostic test to place the test location and control location in a field of view of the mobile phone camera;
- and
- wherein the imaging software extracts regions of interest from the test location and the control location in an image of the field of view and compares respective regions of interest with respective threshold values and characterizes the rapid diagnostic test.

- a modular housing configured to mount to the mobile phone, the modular housing including a receptacle configured to receive a rapid diagnostic test, the rapid diagnostic test comprising a test location and a control location;
- a first illumination source disposed in the modular housing and configured to transmit illumination through the rapid diagnostic test and onto the camera in a transmission mode;
- a second illumination source disposed in the modular housing and configured to reflect illumination off the rapid diagnostic test and onto the camera in a reflection mode
- a switch for actuating the first illumination source and the second illumination source;
- and
- wherein the imaging software extracts regions of interest from the test location and the control location in an image of the field of view and compares respective regions of interest with respective threshold values and characterizes the rapid diagnostic test.
