Researchers from Emory University and Georgia Tech have developed an innovative smartphone app that screens for anemia through images of fingernail beds. This method utilizes an AI algorithm that analyzes the color of the fingernail bed, which indicates hemoglobin levels. The app, tested on over 9,000 users, demonstrates high sensitivity and specificity, matching conventional blood tests. Now publicly available after licensing to Sanguina, this technology is expected to simplify anemia diagnostics, particularly benefiting individuals with chronic conditions, as it eliminates the need for lab access and insurance.
Anemia affects over 2 billion globally, but a new app allows screening through fingernail images, aiming to simplify diagnosis without traditional blood tests.
The AI-powered app, tested on 9,000 users, compares fingernail selfies to clinical blood tests, achieving sensitivity and specificity comparable to traditional methods.
