What is considered a normal fasting glucose level?

Under 5
Between 5 and 6
Less than 7
Less than 10

The correct answer is: Less than 7

A normal fasting glucose level is considered to be less than 7 mmoles per liter. This threshold is consistent with the guidelines set by health organizations that categorize fasting plasma glucose levels. A fasting glucose level below this value indicates that the body's regulation of blood sugar is functioning adequately and that there is no indication of prediabetes or diabetes. Values above this range may indicate potential metabolic disorders, while levels below it show normal physiological functioning in glucose metabolism. This standard helps healthcare providers diagnose and manage conditions related to dysregulated blood sugar levels, which are crucial for maintaining overall health. The other ranges mentioned do not align with the established guidelines and could lead to misinterpretation of an individual's health status.
