Not that we’re aware of, KJ. In the U.S., they don’t use A1c’s diagnostically (although they do in Europe). It’s possible that your problem began recently enough that your last A1c didn’t show it. Here’s what the American Diabetes Association says:
"With the FPG (fasting plasma glucose) test, a fasting blood glucose level between 100 and 125 mg/dl signals pre-diabetes. A person with a fasting blood glucose level of 126 mg/dl or higher has diabetes.
In the OGTT (oral glucose tolerance test) test, a person’s blood glucose level is measured after a fast and two hours after drinking a glucose-rich beverage. If the two-hour blood glucose level is between 140 and 199 mg/dl, the person tested has pre-diabetes. If the two-hour blood glucose level is at 200 mg/dl or higher, the person tested has diabetes."
If I were you, I would make an appointment to see an endocrinologist or diabetologist. While most family practitioners treat people with diabetes, they aren’t necessarily up to speed on current best practices the way these specialists are.
