Question: 1 / 625

What is the fasting blood glucose level that indicates hyperglycemia?

5 mg/dL

6 mg/dL

7 mg/dL

A fasting blood glucose level of 7 mg/dL is the threshold that indicates hyperglycemia, which is defined as an elevated level of glucose in the blood. According to medical guidelines, specifically those set by the American Diabetes Association, a fasting plasma glucose level of 7.0 mmol/L (or 126 mg/dL) or higher is considered to confirm a diagnosis of diabetes.

In the context of these choices, 7 mg/dL represents a critical point in determining hyperglycemia. Levels below this value are generally considered normal fasting glucose levels. Therefore, anything at or above this threshold signifies hyperglycemia, reflecting a possible metabolic disorder or diabetes.

To clarify the context with the other values, levels below 7 mg/dL would generally indicate normal glucose metabolism, while values above imply increasing levels of concern regarding an individual’s glycemic control and the potential need for further investigation or intervention.
