Biomedical engineering students at Johns Hopkins have developed a non-invasive screener for anemia involving a cell phone app called HemoGlobe. Working out of Johns Hopkins University, they have also had seed funding from the Bill and Melinda Gates Foundation and USAID. The test shines light through the skin, detecting the reflection of various wavelengths. Post-detection, the app displays an easy-to-read measure of severity of anemia. Additionally, it sends a message to a central server, which produces a map of anemia cases.
The HemoGlobe team was recently awarded a $250,000 seed grant at the Saving Lives at Birth competition. They hope to sell the cell-phone based system for $10 to $20 each.
