Remember, testing for diabetes should be carried out in a health care setting!
The A1C test measures your average blood glucose for the past 2 to 3 months. The advantages of this test is that you don’t have to fast or drink anything.
- Diabetes is diagnosed at an A1C of greater than or equal to 6.5%
|Normal||less than 5.7%|
|Prediabetes||5.7% to 6.4%|
|Diabetes||6.5% or higher|
The higher the A1C is, the higher the risk for complications. Decreasing your A1C by just 1% will significantly reduce your risk of:
- heart disease
- eye disease
- kidney problems
- nerve damage
- cardiovascular disease
Your Fasting Plasma Glucose (FPG)
This test checks your fasting blood glucose levels. with this test you cannot have anything to eat or drink (except water) for at least 8 hours before the test.
- Diabetes is diagnosed at fasting blood glucose of greater than or equal to 126 mg/dl
|Result||Fasting Plasma Glucose (FPG)|
|Normal||less than 100 mg/dl|
|Prediabetes||100 mg/dl to 125 mg/dl|
|Diabetes||126 mg/dl or higher|
Your Oral Glucose Tolerance Test (OGTT)
The OGTT is a two-hour test that checks your blood glucose levels before and 2 hours after you drink a special sweet drink. It tells the doctor how your body processes glucose.
- Diabetes is diagnosed at 2 hour blood glucose of greater than or equal to 200 mg/dl
|Result||Oral Glucose Tolerance Test (OGTT)|
|Normal||less than 140 mg/dl|
|Prediabetes||140 mg/dl to 199 mg/dl|
|Diabetes||200 mg/dl or higher|
Random (Casual) Plasma Glucose Test
This test is a blood check at any time of the day when you have severe diabetes symptoms.
- Diabetes is diagnosed at blood glucose of greater than or equal to 200 mg/dl
