According to the American Diabetes Association, what is the fasting plasma sugar level indicative of diabetes mellitus?

A fasting plasma sugar level of 126 mg/dl is the threshold set by the American Diabetes Association (ADA) for the diagnosis of diabetes mellitus. This level indicates that the body is not effectively managing glucose levels and reflects a state of hyperglycemia that can lead to the long-term complications associated with diabetes if not properly addressed.

The fasting plasma glucose test is one of several criteria used to diagnose diabetes, and a result of 126 mg/dl or higher on two separate tests is considered diagnostic of diabetes. It's essential to differentiate this level from those designated as normal or prediabetic; for example, normal fasting glucose levels are less than 100 mg/dl, while prediabetes is typically indicated when levels range from 100 to 125 mg/dl. Understanding this range is critical for correct assessment and management in clinical practice.
