Researchers are developing a cross-platform app to test for anemia with a photo



Emory University researchers have developed a cross-platform mobile app that allows anyone to test for anemia with just one photo of their fingernails.

Anemia, the world's most common blood disorder, affects nearly 2 billion people, and is caused by a lack of red blood cells or hemoglobin. The report describes how patients who previously needed an invasive blood test to measure hemoglobin levels can now easily take a photo to "analyze fingernail color and metadata"

Affected> 2 billion people. Our app estimates the hemoglobin value by analyzing the color and metadata of smartphone photos with fingernail beds and detects anemia (hemoglobin values ​​<1

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

While these technical figures can only be easily interpreted by a knowledgeable physician, understanding the accuracy of the app helps clarify its usefulness.

The four-week study involved 337 people with a range of blood disorders, including 72 healthy controls. The researchers report that the app performs better for physicians who rate hemoglobin levels as part of a physical exam – though this is not as good as a blood test. However, it is as good as or even better than a range of FDA-approved diagnostic tools on the market today

Robert Mannino of Emory University has shown a video on YouTube showing the app in action.

Android concerns vs. iOS Availability may also be nipped in the bud, as the document later states:

Android Studio's integrated open source development environment (Google, Mountain View, CA) has become Development of a beta version of the Hgb measurement app in used 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

. It is important that this is just a study and the app is not available to the public. The above video seems promising enough to suggest that we could all access this technology soon. I personally think Apple is very fascinated by this technology and would not be surprised to see that such features will be integrated into iPhone in the future.
