What is HbA1c?

HbA1c is another unit used to measure your blood glucose. It is what’s known as glycated haemoglobin. This is something that’s made when the glucose (sugar) in your body sticks to your red blood cells. Your body can’t use the sugar properly, so more of it sticks to your blood cells and builds up in your blood. Red blood cells are active for around 2-3 months, which is why the reading is taken quarterly. HbA1c is your average blood glucose (sugar) levels for the last two to three months. If you have diabetes, an ideal HbA1c level is 48mmol/mol (6.5%) or below. A high HbA1c means you have too much sugar in your blood. This means you’re more likely to develop diabetes complications, like serious problems with your eyes and feet.

Normal: <42mmol/mol

You do not have diabetes.  Continue the diet/ lifestyle you are currently following.

Pre-Diabetes: 42-47

Your HbA1c is in the Pre-Diabetic Range. You are at an increased risk of developing Type 2 Diabetes in the future.

Have a look at our pages on health and well-being, plus how to potentially put your Type 2 diabetes into remission.

Diabetes: 48 or above

You have type 2 diabetes. Sometimes a second confirmationary blood test is needed.  It may be still possible to get your sugar levels back to normal. Have a look at our Type 2 diabetes remission page.
