THE CLOSER blood glucose levels are monitored and controlled in persons with insulin-dependent diabetes, the better are chances of reducing long-term complications of the disease. Current methods rely on frequently obtaining a drop of blood—an invasive procedure. But several methods of measuring glucose concentration noninvasively are being developed.
"The genesis of the concept started with ear oximetry. You put a photoelectric device on your earlobe and you can tell the oxygen saturation of the blood. It gives us lots of clinical information and it doesn't require a needle stick. We would love to have a similar device for children with diabetes," said Robert A. Goldstein, MD, posing the essence of the research challenge. Goldstein, who is vice president for research at the Juvenile Diabetes Foundation in New York, NY, was interviewed during a meeting last month in Arlington, Va, at which investigators reviewed new proposals for monitoring blood glucose.
