Diabetes: Elevated fasting blood glucose levels may suggest diabetes. In such cases, additional testing may be needed to confirm the diagnosis and determine the type of diabetes.
Prediabetes: Slightly elevated blood glucose levels can indicate prediabetes, a condition in which blood sugar is higher than normal but not yet in the diabetes range.
Hypoglycemia: Abnormally low fasting blood glucose levels may suggest hypoglycemia, which can be caused by various factors, including medications and certain medical conditions.
