DIABETES TEST
You’ll need to get your blood sugar tested to find out for sure if you have prediabetes or type A, type B, or gestational diabetes. Testing is simple, and results are usually available quickly.
Tests for Type A Diabetes, Type B Diabetes, and Prediabetes
Your doctor will have you take one or more of the following blood tests to confirm the diagnosis:
A1C Test
The A1C test measures your average blood sugar level over the past 2 or 3 months. An A1C below 5.7% is normal, between 5.7 and 6.4% indicates you have prediabetes, and 6.5% or higher indicates you have diabetes.
Fasting Blood Sugar Test
This measures your blood sugar after an overnight fast (not eating). A fixed blood sugar level of 99 mg / dl or less than normal, 100 to 125 mg / dl means you have prediabetes, and 126 mg / dl or more means you have diabetes.
Glucose addition test
It measures blood sugar levels before and after drinking fluids containing glucose. You will fast (do not eat) all night before the test and take blood to check your fasting sugar levels. Then drink the fluid and check your blood sugar 1 hour, 2 hours and maybe 3 hours later. Within 2 hours, a blood sugar level of 140 mg / dl or less than normal, 140 to 199 mg / dl means you have prediabetes, and 200 mg / dl or more means you have diabetes. Random blood sugar test
It measures your blood sugar at the time you are tested. You can try it at any time and you don't have to fast (don't eat) first. A blood sugar level of 200 mg / dl or higher means you have diabetes.

If your doctor thinks you have type A diabetes, your blood may also be tested for autoantibodies (substances that show that your body is attacking itself), which are common in type A diabetes but not in type B diabetes. You can test your urine for ketones (produced when your body burns fat for energy), which also suggests type A diabetes instead of type B diabetes.
Tests for gestational diabetes
Gestational diabetes is diagnosed by blood tests. You can be tested between the 24th and 28th week of pregnancy. If your risk of developing diabetes is higher (due to a higher risk factor), your doctor may test you sooner. Your blood sugar level, which is higher than normal at the beginning of your pregnancy, can cause you to be tested in your urine for ketones (which are made when your body burns fat for energy), which also suggests type A diabetes.
Glucose addition test
It measures blood sugar levels before and after drinking fluids containing glucose. You will fast (do not eat) all night before the test and take blood to check your fasting sugar levels. Then drink the fluid and check your blood sugar 1 hour, 2 hours and maybe 3 hours later. Results may vary depending on the amount of glucose you drink and how often your blood sugar is measured. Ask your doctor what your test results mean.
Prevention of type B diabetes
If your test results show that you have prediabetes, ask your doctor or nurse if a life change program is offered in your community through the CDC-led National Diabetes Prevention Program. You can also find an online or personal program. Prediabetes puts you at greater risk of developing type 2 diabetes, but participating in the program can reduce your risk by up to 58% (71% if you are over 60 years old).
