A scientific program allows you to detect anemia by taking a picture of your nails

The cell phones, which are always more vital in our lives, now serve to detect anemia by the levels of hemoglobin with a simple picture of the nails. This is done thanks to a new application, according to a study published by Nature.

The new tool, still under trial and developed at Emory University in Atlanta (USA), could replace the traditional blood tests "in situ", nowadays it is necessary to diagnose and monitor patients with anemia.

This type of evidence that the authors remind, require special material, is more invasive and its effectiveness is often dependent on the available economic resources that pose problems in rural or poor areas, where there are more cases of this disease that affect to more than 2 billion people around the world.

In order to overcome these obstacles, the main experience of the Wilbur Lam project and its colleagues has developed an algorithm that calculates the concentration of hemoglobin in the blood by analyzing the color and technical data of nails captured in the photos.

Users that they emphasize can download the application that activates the mentioned algorithm on their phones or in any other device. Scientists at Emory University tried this tool to one hundred people and found that it evaluated hemoglobin concentrations with high precision, comparable to current methods to detect anemia.

In an additional attempt, which participated in four participants, the application also showed high levels of precision when it was used to track patients.

This tool, they say, will facilitate the anemia diagnosis in regions that lack specialized equipment and trained personnel, allowing those affected to control their hemoglobin levels in isolated devices in less than one minute.

At the moment, they need, more clinical evidence is needed to confirm their accuracy in larger population samples, with the goal of replacing traditional blood tests.
