In the developing world, many people with health problems never receive an accurate diagnosis or appropriate treatment because clinicians lack tools to detect and diagnose diseases and conditions quickly, accurately, and inexpensively. Sophisticated medical tests that could help improve care are not only often unaffordable, they require extensive laboratory facilities and deliver results days later – a hardship for people who may live many miles from the nearest health clinic. Dr. Kelso's team is developing rapid, affordable, point­-of-­care systems for both immunological and molecular tests. The project's objective is to design low­-cost delivery platforms that can perform assays in resource­-poor settings.
