Having high blood glucose or high blood sugar levels is the primary indicator of diabetes. For this reason, all the tests conducted to diagnose diabetes involve checking blood glucose levels. However, in order to determine whether it’s type 1 or type 2 diabetes, further tests need to be done.
Lt Col Reynolds
Some providers may use only one kind of test to check blood glucose levels, but others will use more than one kind of test to verify results. If you have symptoms of diabetes, your provider may use one or any combination of the following tests to measure your blood glucose levels:
- A1C, or glycohemoglobin
- Fasting plasma glucose, or FPG, and
- Random plasma glucose, or RPG
Maj Hemstad If these blood glucose tests indicate diabetes, the next step is to determine whether it’s type 1 or type 2 diabetes. One test for type 1 diabetes looks for destructive immune system cells called autoantibodies that are commonly associated with type 1 diabetes. Another test screens for certain byproducts called ketones in the urine, which indicates a complication of type 1 diabetes called ketoacidosis.
