who will get diabetes- what points the way

The 1-Hour Glucose Tolerance Test Not the Fasting Glucose Testing Accurately Identifies Diabetes Risk

Most doctors who screen you for diabetes give you a fasting glucose test or an A1c test--though the American Diabetes Association specifically states that the A1c test should not be used for diagnosing diabetes. But research 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.
