Long-Term Sugar Marker (HbA1c) Test – Diabetes Blood Test in Birmingham
The HbA1c Test (also known as the long-term sugar marker) is a fundamental blood test used to diagnose and monitor diabetes. Unlike a single blood sugar reading, it shows your average glucose levels over the past 2–3 months, giving you and your clinician a clearer picture of how well your body is managing blood sugar.
Whether you’re being tested for the first time or are already managing diabetes, the HbA1c Test at OneMedicine helps guide treatment decisions and keeps you on track with your health.
What is the HbA1c test?
The HbA1c test measures the percentage of sugar (glucose) that’s attached to your red blood cells. Because red blood cells live for around 2–3 months, the result reflects your long-term blood glucose control rather than just a snapshot like a random glucose test.
It’s a simple, quick blood test that doesn’t require fasting, so you can have it any time of day
What does the HbA1c result mean?
Your HbA1c result helps categorise your blood sugar control:
Normal – HbA1c within the healthy range
Prediabetes – higher than normal but not yet diabetes
Diabetes – elevated levels consistent with diabetes or poor control
These categories help your clinician tailor lifestyle advice, further testing or treatment plans.
If you already know your results, speak to your clinician at OneMedicine about what they mean for your care plan.

Are at risk of type 2 diabetes (e.g., age, family history, weight)
