The Hemaapp [1] is a smart phone application that measures the hemoglobin level in your finger by using the phone’s built-in camera and flash. The hemoglobin measurement is done noninvasively, by placing the finger of the patient on the camera of the phone. The light from the flash allows the camera to record the absorption of light by the blood, while the Hemaapp application analyzes the images to determine the level of hemoglobin. The application was developed at the University of Washington’s Ubiquitous Computing Laboratory. The University of Washington team worked with the NGO, Asociacion Red Innova, to test the innovative technology in the field. The team conducted a field deployment in a variety of diverse settings in Peru, including two communities in the Amazon region, an urban-slum community in Lima, and three clinics in Lima. The following report was drafted to reflect the lessons learned in the field.
