What is the standard range for fasting blood glucose levels in a non-diabetic individual?

The standard range for fasting blood glucose levels in a non-diabetic individual is 70-99 mg/dL. This range indicates normal glucose metabolism and is used by healthcare professionals to assess whether an individual may be at risk for diabetes. Fasting blood glucose levels measure the amount of glucose present in the blood after a period of not eating for eight hours or more.

Values below this range could indicate hypoglycemia, which is a condition characterized by abnormally low blood sugar. Conversely, fasting blood glucose levels that fall within the 100-125 mg/dL range are recognized as indicative of prediabetes, suggesting that the body's ability to manage blood sugar is impaired but not to the extent of diabetes. Levels at or above 126 mg/dL on two separate tests would qualify for a diabetes diagnosis.

Understanding these ranges is crucial for identifying potential health issues early, allowing for timely intervention and management.
