Diabetes (HbA1c)

Could You Have Diabetes and Not Know It?

Over 1 million people in the UK have undiagnosed diabetes — slowly damaging their health without realising it. A simple blood test can catch it early, giving you the power to protect your body and your future.

What this test includes:

This test measures your HbA1c, a key marker that shows your average blood sugar levels over the past 2–3 months. It helps with:

• Diagnosing Type 2 diabetes, which often develops silently over several years
• Monitoring existing diabetes, making sure treatment and lifestyle changes are working

Whether you’re checking for the first time or managing a known condition, this test gives essential insight.

Why get tested?

Diabetes damages the small blood vessels throughout your body — affecting the heart, kidneys, eyes, and nerves. Most people with Type 2 diabetes don’t realise they have it until years later, after harm has already been done.

Type 2 is the most common form (90% of cases) and is influenced by lifestyle and genetics. Type 1 diabetes is autoimmune, and while less common, also requires regular monitoring.

Catching diabetes early means you can start treatment, improve how you feel day-to-day, and prevent long-term complications.
