Emory University researchers have developed a mobile platform application that can test someone for anemia with just one photo of their nails.

Anemia, which is the most common blood problem in the world, affects almost 2 billion people, and is caused by lack of red blood cells or hemoglobin. The report describes how patients who previously demanded an invasive blood sample to determine hemoglobin levels can easily snap a photo to “analyze the color and metadata of the fingernail.”

We initially targeted anemia, a blood ratio characterized by low blood hemoglobin levels affected> 2 billion people. Our app estimates hemoglobin levels by analyzing color and metadata on the fingernail’s smartphone photos and detecting anemia (hemoglobin levels <1

2.5 g dL -1 ) with an accuracy of ± 2.4 g dL -1 and a sensitivity of 97%

While these technical numbers are easily interpreted by a knowledgeable medical professional, you get an insight into how the app’s accuracy was verified helps clarify usability.

The four week study included 337 people with a number of blood disorders, including 72 healthy control subjects. The researchers report that the app surpassed physicians who assessed hemoglobin levels from a physical exam, although it is not as good as a blood sample. But it’s as good as, or even better than, a number of FDA-approved diagnostic tools on the market today

Emory University’s Robert Mannino shared a video on YouTube that shows the app in action.

Concerns about Android vs. iOS Availability can be siphoned in the bid because the document later states:

The open source (IDE) Android Studio (Google Mountain View, CA) integrated development environment was used to develop a beta version of Hgb- the measurement device in the Android operating system. The proprietary IDE Xcode (Apple, Cupertino, CA) was used to develop a beta version of the app in the iOS operating system

What is important to note here is that this is just a study and the app is unavailable to the public . The video above seems promising enough to insulate that we all soon have access to this technology. Personally, I think Apple is very fascinated by the technology of this kind and would not be surprised to see features built into iPhones in the future.
