Systems and methods for quantitative diagnosis of anemia

A system for analyzing an image for estimating hemoglobin levels, the system comprising at least one processor configured to:

• access a camera of a mobile device;
• force on a flash functionality of the camera to normalize variable background lighting conditions;
• capture, via the camera, an image of one or more fingernail beds of a user with the flash on, wherein:
• the camera automatically uses at least one lighting condition setting;
• and
• the mobile device automatically associates metadata with the image, the metadata comprising information about the flash and the at least one lighting condition setting;
• receive the image from the camera;
• determine pixel intensity for each of one or more regions of interest;
• transform an average pixel intensity from color channels across each of the one or more regions of interest into a value that correlates with the user's approximate hemoglobin (Hgb);
• adjust the value based on the metadata associated with the image to compensate for the at least one lighting condition setting and the flash;
• determine the user's approximate Hbg level from the image based on the adjusted value;
• and
• output the user's approximate Hgb level to a display of the mobile device.
