Why this test
Prediabetes affects around 2 million Australians — and most don't know they have it.
Fasting blood sugar (glucose) measures the amount of glucose in your blood after an overnight fast. It is the standard first-line test for detecting impaired glucose tolerance and type 2 diabetes risk. Caught early, elevated fasting glucose is highly modifiable through lifestyle changes.
Understanding your results
Optimal
Your fasting glucose is in the ideal range for metabolic health
Low-normal
Your fasting glucose is within range on the lower side — mention to your healthcare practitioner if you have symptoms
Below reference range
Low fasting glucose may warrant discussion with your healthcare practitioner
Above reference range
Results of 5.5–6.9 mmol/L may indicate impaired fasting glucose; ≥7.0 may suggest further evaluation is warranted — discuss with your healthcare practitioner
Reference ranges vary by laboratory and personal context. Your result is shown against the lab's range in your dashboard, alongside what it means.

No — fasting BSL reflects your glucose level at a single point in time, while HbA1c reflects your average blood sugar over the past 2-3 months. Together they provide a more complete metabolic picture.
Yes. Acute illness, significant stress, or certain medications can temporarily elevate blood glucose. If your result is unexpected, your healthcare practitioner may recommend a repeat test.
If your result is normal and you have no risk factors, every 3 years from age 40 is typical. With risk factors (family history, overweight, gestational diabetes history), your healthcare practitioner may recommend more frequent testing.
