LOS ANGELES, May 13 (Xinhua) -- U.S. researchers have developed an AI-augmented smartphone app capable of noninvasively estimating blood hemoglobin levels and screening for anemia based on photos of users' fingernails, according to a new study published Tuesday in Proceedings of the National Academy of Sciences (PNAS).
The app demonstrated high accuracy when compared to self-reported complete blood count results from 9,061 users. Over 1.4 million uses of the app also enabled the creation of a real-time anemia prevalence map across the United States, the study noted.
