All of the above tests need to be repeated to confirm if you have diabetes. The use of A1c for diagnosing diabetes is not recommended at this time. The oral glucose tolerance test (OGTT) may be a better test to determine if an individual of Asian descent has diabetes or pre-diabetes because the fasting plasma glucose test sometimes can miss the diagnosis especially in this population.
