Blood Test Results That Identify Prediabetes

Part of the Prediabetes For Dummies Cheat Sheet

Prediabetes is a silent condition: You likely will not experience any symptoms from it. But allowing prediabetes to develop into diabetes will most definitely lead to symptoms, which is exactly what you want to avoid.

If you’re concerned that you may be at risk for prediabetes, ask your doctor to order a blood test. Two types of blood tests are used: a fasting blood glucose test (which is taken after you fast overnight) and a blood glucose test taken two hours after you consume 75 grams of glucose.

Following are the lab results your doctor will use to determine if your blood glucose is normal, if you have prediabetes, or if you have diabetes.

Normal Prediabetes Diabetes
Fasting blood glucose Less than 100 mg/dl 100–125 mg/dl 126 mg/dl or greater
Blood glucose two hours after eating 75 grams of glucose Less than 140 mg/dl 140–199 mg/dl 200 mg/dl or greater
