Smartphone cameras may help assess anemia using new app

Written by Celeste Brady, Commissioning Editor

Researchers at Purdue University (IN, USA) have developed a program that can assess a patient's hemoglobin level by taking a photo of their inner eyelid. The software could supplement blood tests as a less invasive and faster means of diagnosis for blood disorders, such as anemia. A team of researchers and engineers at Purdue University (IN, USA) has developed software that uses an image of a patient’s inner eyelid to give a blood hemoglobin count using spectroscopic analysis. Published in Optica, the team employed super-resolution spectroscopy, which converts low-resolution smartphone photos into high-resolution digital signals. These signals show the absorption...
