  • Patent number: 11954851
    Abstract: A diagnostic system performs disease diagnostic tests using at least an optical property modifying device and a mobile device. A user provides a biological sample from a patient to the optical property modifying device that reacts with a reagent in one or more reaction chambers of the device. The user captures one or more images of the one or more reaction chambers using an optical sensor of the mobile device. The diagnostic system can determine a quality level of the images based on factors such as skew, scale, focusing, shadowing, or white-balancing. Based on an analysis of the captured image, the diagnostic system can determine a test result of a disease diagnostic test for the patient. The diagnostic system may communicate the test result, as well as instructions for the disease diagnostic test, to the user via the mobile device.
