Frequently asked questions
Can a routine blood test detect diabetes?
If you believe you are at risk of developing diabetes, you can test your blood sugar levels with our simple finger-prick, Diabetes (HbA1C) Blood Test. It measures the amount of sugar that is attached to the haemoglobin in red blood cells and comes with results and next steps from a qualified doctor. A formal diagnosis must be confirmed through a medical consultation. Find out how you can reduce your risk of type 2 diabetes.
Is fasting required for a diabetes blood test?
You do not need to fast for an HbA1C blood test, which identifies blood sugar levels over the previous 8-10 weeks. However, you would need to fast for the fasting plasma glucose (FPG) test, which measures blood sugar after you’ve fasted for 8 hours. Learn more about how diabetes is diagnosed and treated.
When should I do a diabetes blood test?
You may want to do a diabetes blood test if you have a family member with type 2 diabetes or if you have any type 2 diabetes symptoms, like:
- Increased hunger, thirst, or urination
- Blurry vision
- Sores that are slow to heal
- Recurrent infections
What can a diabetes blood test result show?
Diabetes blood test results could show if your blood glucose level is too high or if it is within the normal range. Your doctor can use the test results to help diagnose diabetes and pre-diabetes. Pre-diabetes describes the transition between not having diabetes and having it. If you detect it early, you can reverse pre-diabetes through lifestyle changes.
