Scientists have developed a smartphone app that can only detect a person's blood hemoglobin level with a single photo of the nails. Thanks to this, it is possible to diagnose anemia without having to use blood tests.
The idea of the application was born because of the health problems of one of the researchers involved. Rob Mannino suffers from beta-thalbademia, a disease that can lead to anemia.
"Treatment of my disease requires monthly blood transfusions," says Mannino. "Doctors would do more tests of my hemoglobin levels if they could, but it's complicated to go to the hospital, between two transfusions, for a blood test. , my doctors rather estimate when I am going to need the transfusion. "
With pictures taken before and after transfusions, while hemoglobin levels were changing, he was able to constantly perfect the technology, "says Wilbur Lam of Emory University.
With a precision similar to traditional methods, the application – which should be commercialized in 2019 – should not be used for the initial diagnosis, say the researchers, but only for patients. </ p> <p> The study was published in the journal Nature Communications
