There are several ways to diagnose diabetes. Each way usually needs to be repeated on a second day to diagnose diabetes. Show Testing should be carried out in a health care setting (such as your doctor’s office or a lab). If your doctor determines that your blood glucose (blood sugar) level is very high, or if you have classic symptoms of high blood glucose in addition to one positive test, your doctor may not require a second test to diagnose diabetes. A1CThe A1C test measures your average blood glucose for the past two to three months. The advantages of being diagnosed this way are that you don't have to fast or drink anything.
Fasting Plasma Glucose (FPG)This test checks your fasting blood glucose levels. Fasting means after not having anything to eat or drink (except water) for at least 8 hours before the test. This test is usually done first thing in the morning, before breakfast.
Oral Glucose Tolerance Test (OGTT)The OGTT is a two-hour test that checks your blood glucose levels before and two hours after you drink a special sweet drink. It tells the doctor how your body processes sugar.
Random (also called Casual) Plasma Glucose TestThis test is a blood check at any time of the day when you have severe diabetes symptoms.
What is Prediabetes?Before people develop type 2 diabetes, they almost always have prediabetes—blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes. Doctors sometimes refer to prediabetes as impaired glucose tolerance (IGT) or impaired fasting glucose (IFG), depending on what test was used when it was detected. This condition puts you at a higher risk for developing type 2 diabetes and cardiovascular disease. SymptomsThere are no clear symptoms of prediabetes, so you may have it and not know it. Some people with prediabetes may have some of the symptoms of diabetes or even problems from diabetes already. You usually find out that you have prediabetes when being tested for diabetes. If you have prediabetes, you should be checked for type 2 diabetes every one to two years. Results indicating prediabetes are:
Preventing Type 2 DiabetesYou will not develop type 2 diabetes automatically if you have prediabetes. For some people with prediabetes, early treatment can actually return blood glucose levels to the normal range. Research shows that you can lower your risk for type 2 diabetes by 58% by:
Don't worry if you can't get to your ideal body weight. Losing even 10 to 15 pounds can make a huge difference. A fasting blood sugar (FBS) level is the result of a blood sample taken after a patient fasts for at least eight hours. A normal fasting blood sugar level for someone without diabetes is less than 100 mg/dL, or HbA1C below 5.7%. Prediabetes is a fasting blood sugar level from 100 to 125 mg/dL, or HbA1C of 5.7%-6.4%. Diabetes is a fasting blood sugar level of 126 mg/dL and above, or HbA1C of 6.5% or higher. Source:

What is a normal fasting blood glucose for a person with diabetes?According to the American Diabetes Association (ADA) guidelines, patients with diabetes should strive to achieve fasting blood glucose levels below 131 mg/dL, and levels following meals below 180 mg/dL.
