HbA1c blood test explained: what it measures and what your results mean

The HbA1c blood test measures your average blood glucose levels over the past two to three months. It's a useful tool for understanding long-term blood sugar control, especially for those managing conditions like diabetes. In UK clinical practice, HbA1c values are often discussed using specific thresholds to guide treatment decisions, but it's important to remember that one result is just a snapshot. Your GP or diabetes care team can interpret whether these thresholds apply to you.
