What is the normal range for blood glucose levels in adults fasting?

The normal range for fasting blood glucose levels in adults is 70-100 mg/dL. This range is accepted as the standard for individuals who have not consumed any food for at least eight hours. Fasting blood glucose tests are critical for diagnosing and managing conditions like diabetes and hypoglycemia.

Blood glucose levels below or above this range can indicate underlying health issues. For example, levels under 70 mg/dL may suggest hypoglycemia, while levels above 100 mg/dL may be indicative of prediabetes or diabetes. Understanding this range is vital for healthcare professionals in making informed decisions about patient care and treatment strategies.
