What Is Diabetes Mellitus?
Reviewed: Dr. Gromatzky
6. Diagnosis
The criteria for the diagnosis of diabetes per the American Diabetes Association are any of the following: A fasting plasma glucose of 7.0 mmol/L or higher, 2-hour plasma glucose level of 11.1 mmol/L or higher, HbA1c level of 6.5% or higher, or a random plasma glucose level of 11.1 mmol/L or higher in those with symptoms of hyperglycemia. Repetition of the test can be performed for confirmation purposes (on a different day).
Confirmation can also be achieved when the results of 2 different tests are above the threshold for diagnosis. Those with levels higher than normal but below the criteria to be diagnosed with diabetes are considered to have impaired fasting glucose or impaired glucose tolerance.
