What is the normal blood glucose level range?

The normal blood glucose level range is widely accepted to be between 80 and 120 mg/dL. This range reflects the typical physiological levels of glucose in the bloodstream for a healthy individual who has not eaten for a period of time (fasting state). Maintaining blood glucose within this range is crucial for the body's metabolic processes and overall health.

When glucose levels fall below or rise above this normal range, it can lead to various health issues. Levels below 70 mg/dL may indicate hypoglycemia, while levels consistently above 126 mg/dL can suggest hyperglycemia, often associated with diabetes.

Options that provide values outside this recognized range, such as 160 to 200 mg/dL or 30 to 150 mg/dL, do not accurately represent normal blood glucose levels. Similarly, a range of 60 to 80 mg/dL, while it includes a segment of the normal range, does not encompass the complete spectrum needed for a healthy glucose level. Therefore, the selection of 80 to 120 mg/dL as the normal range aligns with standard clinical guidelines and practices in assessing blood glucose levels.
