What is one diagnostic criterion for type 2 diabetes?

A diagnostic criterion for type 2 diabetes is a blood glucose level measurement. This is fundamental because diabetes, particularly type 2, is characterized by elevated blood glucose levels due to insulin resistance or insufficient insulin production.

The diagnostic process may include measuring fasting blood glucose, a glucose tolerance test, or checking HbA1c levels to assess long-term glucose control. These measurements provide critical information about an individual’s carbohydrate metabolism and are instrumental in confirming a diagnosis of diabetes.

In contrast, while the other options may be relevant in the context of overall health evaluation, they do not specifically serve as diagnostic criteria for diabetes. For example, the presence of influenza relates to infectious disease processes rather than metabolic disorders. Kidney function tests check for renal health, which can be affected by diabetes but do not diagnose it directly. Blood pressure measurements are important for assessing cardiovascular risk and overall health but do not indicate diabetes status on their own.
