About the test

Diabetes is a major problem around the world. A combination of unhealthy diets and sedentary lifestyles has caused rates of diabetes to sky-rocket in recent decades. This is the advanced version of our HbA1c Blood Test that also measures Glucose, as well as the HbA1c biomarker.

Not only can diabetes make you feel unwell, but high blood sugar levels damage the nerves in the hands and feet, the kidneys, and the eyes, as well as enormously increasing the risk of cardiovascular disease.

The diabetes blood test will help you check for diabetes and for early problems in processing blood sugar known as prediabetes or impaired fasting glucose.

2 Biomarkers


    - HbA1c 


    - Fasting glucose


    Need more biomarkers? Check out our Healthy Lifestyle Blood Test that also measures fasting glucose level and HbA1c together with organ function.


    For most biomarkers our usual turnaround time is 24-48 hours, or less, from the time your sample is in our lab. We do not wait for all the results to complete before sending them to you, so you may start receiving results the same day for most cases, or as results become available.

    We are extremely proud of our very short turnaround times and a very efficient laboratory processes. Whilst we accommodate the shortest of time scales, with some results available within hours, for this particular test the usual turnaround time is:

    2-3 days

Doctor's notes

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

Detecting the problem early can allow lifestyle changes to be made, and appropriate medical treatment to be given, that can prevent all these problems that are both life impairing and life shortening. Better yet, is to detect a problem with sugar metabolism at an even earlier stage, known as prediabetes, as this allows you to make life saving changes before the disease develops. 

Red flag symptoms for the Advanced Diabetes Blood Test

Even if all the blood tests are normal, you should still see your doctor if you have any of the symptoms below.

  • Unexplained weight loss
  • Progressive fatigue and malaise
  • Passing lots more urine than normal 

Your Results and Health Dashboard

The results of your Advanced Diabetes Blood Test will be emailed to you as a secured PDF file, ready for your GP and will also be uploaded to our Health Dashboard area of the website. It’s a unique and powerful tool, powered by our in-house clinical analysis research, to match your biomarkers across test panels and symptoms, as well as provide clinical commentary on all individual biomarkers you tested for.

The health dashboard will also provide "panel level" commentary - a birds eye view of the biomarkers that were tested. This feature allows you to view your test results and clinical commentary, and compare them to previous results, giving you a clear understanding of how your health is progressing.

By using the Health Dashboard, you can identify changes in your biomarkers and make necessary adjustments to your lifestyle. This added value is immense, as it empowers you to monitor your health and make informed decisions about your well-being.

It's free and is available with all of our tests.

Special instructions

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Advanced Diabetes Blood Test.

This is best done as a fasting test so have nothing to eat and only drink water from 10pm the night before you take the test.

Venepuncture appointment - how to prepare

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit for Advanced Diabetes Blood Test - how it works

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!

Frequently Asked Questions

Hi, I am Lana Nela, Lead Nurse, and here is what we are frequently asked about this test.

If I forget to fast, is the test still valid? 

We interpret the blood glucose level on the assumption that you have fasted, so if you forget to fast then it may lead us to believe there is a problem when there actually isn’t. The fasting glucose also allows us to look for ‘impaired fasting glucose’ which is high blood sugar levels despite having fasted. This is a sign that you are at high risk of progressing to diabetes. A ‘random’ glucose (i.e. taken when you haven’t fasted) can still be useful, a normal result is reassuring but a high result should prompt further investigations. 

What is HbA1c?

HbA1c is also known as glycated haemoglobin. It is a measure of how much of the haemoglobin in your red blood cells is bound to glucose. Because the life of a red blood cell is about 3 to 4 months, the proportion of haemoglobin that is bound to glucose tells us what your average blood sugar levels have been during that period. It can be used to diagnose diabetes, but is also very useful for monitoring the disease over time and assessing your response to treatment. 

What is prediabetes?

Prediabetes means that your blood sugar levels are higher than they should be but not yet high enough to diagnose you with diabetes. It means that the biological changes that lead to diabetes have already started, and you are therefore at high risk of developing diabetes in the future. Discovering that you have prediabetes gives you the chance to make urgent lifestyle changes to ensure that you don’t go onto develop diabetes.

What are the symptoms of diabetes?

In its early stages diabetes may cause no symptoms but common symptoms are tiredness and malaise, feeling thirsty all the time, passing lots of urine, and blurred vision. 

Why take this test?

Hi, I am Dr. Marco Esposito and here is why it's important to take this test.
  • You are worried your symptoms may be due to diabetes
  • You have a strong family history of diabetes
  • You want to monitor your response to treatment or lifestyle changes
  • You are worried your lifestyle has put you at risk of diabetes

Is this test right for you?

Hi, I am Sandeep Patel, I am the Laboratory Director at One Day Tests. Here are the symptoms that you may wish to address with this test.

Diabetes is increasingly common and may result from a combination of genetic predisposition and lifestyle factors.

You may want to take this test if you have a family history of diabetes or if you are worried that your lifestyle has put you at risk of diabetes.
