What does it mean for my glucose test in a Non-fasting Health Screening?

HbA1C is used to screen for diabetes. HbA1C tells us the blood glucose control over the last 3 months by measuring sugar molecules attached to your red blood cells. Concurrently, a non-fasted random blood glucose level is run. The normal cut-off for random blood glucose will be different from fasted blood glucose. 

If your random blood glucose or HbA1C is abnormal, you may be required to do fasting blood glucose to confirm the diagnosis of diabetes or prediabetes.
