New, Cheap Paper-Based Diabetes Test Perfect For Developing Countries
With epidemics of Type 2 diabetes looming in rural India, China and other areas of the world where poverty limits the availability of health care, scientists are reporting development of an inexpensive and easy-to-use urine test ideally suited for such areas. The report describing the paper-based device, which also could be adapted for the diagnosis and monitoring of other conditions and the environment, appears in ACS' journal Analytical Chemistry.
Jan Lankelma and colleagues point out that monitoring glucose levels is important. Although diabetes test strips seem inexpensive, the cost can be prohibitive in areas where people must choose between that and the essentials of life, such as food and shelter. In addition, current handheld diabetes monitoring devices measure glucose levels in blood, which requires a pin-prick to a finger – something that could deter patients from taking the measurements. To address these challenges, the researchers built a new type of glucose monitor – one that detects glucose levels in urine (which is easy to obtain) and is made from inexpensive materials, such as paper.
