What can a HbA1c blood test tell you?

By checking your HbA1c levels regularly, you can understand your risk of pre-diabetes and diabetes.

Type 2 diabetes tends to affect men earlier in their lives than women. But women who have polycystic ovary syndrome (PCOS) have a greater risk of developing type 2 diabetes due to increased insulin resistance.

This test might also be helpful if:

you're over the age of 45 — your risk of diabetes increases with age
you've had gestational diabetes in the past
if you have a parent or sibling with type 2 diabetes
have other medical conditions — like heart disease, high blood pressure, PCOS, or high cholesterol
you're carrying excess weight
you're physically inactive

What's covered in this blood test?

HbA1c refers to glycated haemoglobin. When the glucose (sugar) in your blood rises, it binds to the haemoglobin in your red blood cells. Red blood cells live for about 3 months, so an HbA1c test measures your average blood glucose levels over the last few months.

Want to know more?

An HbA1c test won’t tell you how high your blood sugar is. But it can tell you if your blood sugar has been high over the last 3 months. Some conditions can cause fluctuations in your HbA1c levels.

A doctor won't use this type of test if diagnosing diabetes. This includes if you:

- are pregnant or gave birth in the last 2 months

- have only been experiencing diabetes symptoms for 2 months — like frequent urination or excessive thirst

- take medication that can affect your blood sugar levels — like long-term steroid treatment and some antibiotics

- are currently acutely ill (a sudden and severe sickness)

- have pancreatic problems

- have end-stage kidney disease

- are HIV positive

The ranges for HbA1c levels are defined as:

- normal range = below 42 mmol/mol

- prediabetes = 42-47 mmol/mol

- indicates diabetes = 48 mmol or over

Your data is in safe hands. We use the latest encryption technologies and take our Data Protection obligations seriously.
