Researchers at John Hopkins University in Maryland have developed the HemoGlobe, a small smartphone attachment that can test for anemia. The sensor uses small wavelengths of light, not needles, to detect the level of hemoglobin in a person's blood. The results of the test are sent to a central database for further analysis.
The researchers at Johns Hopkins University estimate that the HemoGlobe could be manufactured for about $10 to $20 a piece. If mass produced, the HemoGlobe could be a big help to health workers in third world countries. A health worker who could use their phone to test for anemia could cover more ground than one who has to continually search for clean needles. The HemoGlobe has a shot at going into production as the team that developed it has won a $250,000 grant from Saving Lives at Birth: A Grand Challenge for Development competition.
