Fasting glucose
What it is
Fasting glucose is the level of sugar in your blood after not eating for 8-12 hours. It is a simple, widely used snapshot of how your body manages glucose at rest.
Why it matters
Raised fasting glucose can be an early sign of impaired glucose regulation. Paired with HbA1c and fasting insulin, it helps build a picture of metabolic health rather than standing alone.
What “optimal” looks like
A healthy fasting range is well established; values are read alongside HbA1c and insulin. A single reading can be affected by stress, sleep and recent activity, so trends are informative.
This is general information, not medical advice or a diagnosis. Always discuss your results with a qualified clinician.
