Need For Improved Screening Method
The greatest opportunity in addressing the burden of diabetes is to focus on primary prevention. Numerous clinical studies have demonstrated that if found early and treated appropriately, diabetes and its complications are preventable.
However, in the U.S, people are grossly under screened for diabetes due to the inconvenience and implementation of current methods. Only 1 in 5 Americans at risk for developing type 2 diabetes are screened each year. Current screening methods require an overnight fast, a separate trip to a reference lab and invasive venous blood draws performed by a trained phlebotomist. The most commonly used screening test, Fasting Plasma Glucose, misses half of patients with undiagnosed diabetes. The Oral Glucose Tolerance Test (OGTT) is an inconvenient procedure that’s not commonly used for screening.
