A scientific application allows you to identify anemia by taking a nail photo


Mobile phones, which have become increasingly important in our lives, now serve to detect anemia based on hemoglobin levels with a simple photograph of the nails. This was done by a new application according to a study published by Nature.

The new tool currently developed and tested in Emory University in Atlanta (USA) can replace the "in situ" traditional blood tests that are currently required to diagnose and monitor anemia patients.

Such evidence reminds authors that they require special materials, are more invasive, and that their effectiveness often depends on existing economic resources that show problems in rural or poor areas where this disease is more likely to affect this disease. More than 2 billion people worldwide.

To tackle these obstacles, Wilbur Lam and his colleagues, who are responsible for the project, developed an algorithm to calculate the hemoglobin concentration in the blood by analyzing the color and technical data of the nail beds captured in the photographs.

They will be able to download the application that activates the algorithm in their phones or any other device, as emphasized by users. Scientists at Emory University have tested this tool on hundreds of people and found that it predicts hemoglobin concentrations with a high degree of accuracy comparable to existing methods to detect anemia.

In an additional test involving four participants, the practice showed a high level of sensitivity when used to monitor patients.

This tool will help diagnose anemia in areas with specialized equipment and trained staff, and will allow them to control hemoglobin levels in remote devices in less than a minute.

For the time being, more clinical testing is needed to confirm the accuracy of larger population samples to replace traditional blood tests, as they need to.
