They said the postage-stamp-sized paper-based device shows promise for use in developing countries and as a way to reduce health care costs in the United States. The test was developed by researchers at Beth Israel Deaconess Medical Center in Boston and Diagnostics for All, a nonprofit based in Cambridge, Mass., dedicated to improving the health of people in developing nations.
