There's an app for that! Using your smartphone to test for Anemia. » Behind the Headlines

I'd be willing to bet that if you were asked to list ten uses for your smartphone, you probably wouldn't include "medical device" in your answer. But as smartphones become increasingly capable, highly-portable computing platforms, researchers are looking to the computer in everyone's pocket as a way to improve global health. As Wired UK declared earlier this year, the next revolutionary medical device is likely to be your smartphone. Scientists have already developed smartphone-based apps that can monitor asthma, detect skin cancer, and diagnose traumatic brain injuries. The latest app that joins the "doctor in your pocket" list is helping screen for anemia.
