A scientific app lets you discover anemia by taking a picture of your nails



Mobile phones, increasingly important in our lives, now serve to detect anemia of hemoglobin levels with a simple fingernail. This is done thanks to a new application, according to a study published by Nature.

The new instrument, which is still under test and developed at the Emory University in Atlanta, can replace the in situ "traditional blood tests that are currently needed to diagnose and monitor patients with anemia.

This type of evidence that reminds the authors requires specialized material is more invasive and their effectiveness often depends on the available economic resources, creating problems in rural or poor areas where there are more cases of this disease that affects more than 2 billion people around the world.

To overcome these obstacles, Project Chief Expert Wilbur Lam and colleagues developed an algorithm that calculates the concentration of hemoglobin in the blood by analyzing the color and technical data of the nails shot in the photos.

Users who underline will be able to download to their phones or any other device the application that activates the algorithm. Scientists from the Emory University tested this tool for hundreds of people and found that he evaluated hemoglobin concentrations with a high degree of accuracy comparable to current methods of detecting anemia.

In an additional test that included four participants, the application showed a high degree of accuracy when used to track patients.

This tool would make it easier to diagnose anemia in regions lacking specialized equipment and trained personnel, allowing those affected to control hemoglobin levels in remote devices in less than a minute.

For the time being, it is necessary to perform more clinical tests to confirm their accuracy in larger population samples in order to replace traditional blood tests.
