  • Diabetes: over 48mmol/L

Frequently asked questions​

This is what our customers ask us most about this test. For more information, try our help centre.

  • What is prediabetes?

    Prediabetes is the stage before type 2 diabetes is diagnosed. During pre-diabetes, your blood glucose levels are increased above normal but are not high enough for a type 2 diabetes diagnosis. Therefore, it is the critical period before diabetes is diagnosed and, if spotted, may be improved with simple changes to your lifestyle.

    Prediabetes is often used to describe two conditions. Impaired fasting glucose (IFT), when your blood glucose levels are increased after a period of fasting, or impaired glucose tolerance (IGT) where your blood sugar levels are increased beyond normal after eating.

    It is not an uncommon condition either, up to 7 million people in the UK are believed to be prediabetic.

  • What is the test for diabetes type 2?

    An HbA1c blood test is the gold standard for diagnosing diabetes type 2. It gives an average measure of your blood glucose levels over the last 2-3 months.


  • Is the amount of people with diabetes growing?

    In the UK, 4.7 million people have diabetes and this is expected to rise to 5.5 million within the next decade. 90% of people who have had a diagnosis have type 2 diabetes whereas type 1 accounts for around 8%.

    Yet the actual figure could be higher because there is an estimated one million people living with type 2 diabetes in the UK who haven’t been diagnosed. The prevalence of type 2 diabetes is a problem, not least because it costs the NHS a staggering £173 million per week.

    The increase in obesity is largely to blame for the rise in type 2 diabetes cases. In fact, it is the biggest risk factor for the development of the condition. Yet, by taking control of your own health and understand what’s really going on inside you, you can take positive action to lower your risk by making changes to your lifestyle.

  • What is an HbA1c blood test for?

    An HbA1c test is used to test for prediabetes or type 2 diabetes in adults. Unlike other tests, it gives you an average blood glucose reading over a period of up to three months rather than at the time of testing. It is often considered the gold standard in diabetes testing.


  • What is a healthy HbA1c level?

    For people who do not have type 2 diabetes, a normal HbA1c level is between 20-42mmol/mol.

  • What can cause a high HbA1c level?

    Several factors can contribute to an increase in HbA1c levels such as obesity or being overweight, lack of exercise, an unhealthy diet, diabetes, stress and even some medications.

  • What can I do to reduce my HbA1c level?

    There are several things you can do to help lower your HbA1c level such as eat a healthier diet consisting of low glycaemic index foods, exercise regularly, reduce stress and lose weight are just a few.

    Use our at home HbA1c blood test to monitor and check your HbA1c levels.

Recommended by doctors

"An HbA1c blood test assesses long-term blood sugar control in diabetes. It measures the percentage of haemoglobin with attached glucose over about three months. The result indicates average blood sugar levels during that time, helping doctors identify, monitor and manage diabetes."

How often should I test?

We recommend a follow up test 3 months after your first test, followed by a test every 6 months depending on your results, but its up to you!

Can I change what’s tested in future tests?

Yes, you can tailor/customise subsequent tests (via your app) to focus on just the areas that need improving.
