New Evidence that Post-Challege Glucose Not Fasting Plasma Glucose Accurately Predicts Future Diabetes

Page Changed: What is a Normal Blood Sugar?

Research first published in 2008 that was based on studying a group of 2,442 subjects who were free of type 2 diabetes at the beginning of the study found that fasting glucose tests were a very poor predictor of who in this group would develop diabetes.

The researchers found that people whose one hour glucose tolerance test results were over 155 mg/dl and who had markers for metabolic syndrome--such as a concentration of fat around the belly and high blood pressure were those who were more accurately predicted to be likely to develop diabetes.
