KANSAS CITY, Mo. — The blood test recommended for detecting Type 2 diabetes in overweight children may not be enough, and they may need two different tests to diagnose the disease, according to research conducted at Children's Mercy Hospital and Clinics in Kansas City, Mo.

The researchers found that the hemoglobin A1C test missed more than two-thirds of diabetes cases in children at high risk for the condition, but they found that performing that test along with the oral glucose tolerance test dramatically could lower the risk of delayed diagnosis in overweight children.
