Can You See a Private GP While Registered with the NHS?
We get asked all of the time, “Is it OK that I have an NHS GP?” It absolutely is! It’s
July 7, 2026
Each year, around 5 million glucose tests are carried out in the UK, primarily for diabetes screening and monitoring.
With approximately 4.9 million people in the UK living with diabetes, and 90% of them diagnosed with type 2, keeping on top of your health is more important than ever.
Whether you are managing a chronic condition or just looking to stay on top of your well-being, our dedicated team is here to support you.
Glucose is a simple sugar (monosaccharide) that is a primary source of energy for the cells in your body. It is found in many foods, particularly in carbohydrates. When you eat carbohydrates, your body breaks them down into glucose, which then enters the bloodstream. Insulin, a hormone produced by the pancreas, helps cells absorb glucose from the blood for use as energy or storage.
In addition to being crucial for energy, glucose levels in the blood are tightly regulated. Too little glucose can lead to hypoglycemia, while too much can result in hyperglycemia, which is often associated with diabetes.
Type 1 Diabetes: An autoimmune disorder that destroys insulin-producing cells, requiring lifelong insulin therapy, usually starting in youth.
Type 2 Diabetes: Characterised by insulin resistance and reduced insulin production, type 2 diabetes is the most common form of the condition. It typically develops in adults but is increasingly seen in children and adolescents due to rising obesity rates and sedentary lifestyles.
Gestational Diabetes: High blood sugar during pregnancy that usually returns to normal after childbirth.
Monogenic Diabetes: Caused by genetic mutations affecting insulin production, with varying onset and treatment.
Secondary Diabetes: Resulting from other conditions or treatments, typically managed by addressing the underlying cause and controlling blood sugar.
Diabetes can present with a variety of symptoms, which may vary depending on whether someone has type 1 or type 2 diabetes. Here are some common signs:
Use our online booking engine or book your test by giving us a call.
On the online booking engine select the “appointment type” you need.
You will be seen by one of our friendly phlebotomists or trained clinicians.
Your doctor will provide detailed instructions on how to prepare for your diabetes blood test. Typically, this includes fasting for 8 to 12 hours beforehand. Be sure to inform your doctor of any medications or supplements you are taking, as some can influence blood glucose levels and potentially affect the test results. Unless advised otherwise, drink plenty of water to stay hydrated; this can make the blood draw process smoother. Additionally, avoid consuming sugary or high-carb foods the day before the test to ensure accurate results.
Our blood test, performed at our clinics in London, involves drawing a small sample of blood, typically from a vein in your arm. The process is quick, usually lasting just a few minutes, and you may feel a slight pinch when the needle is inserted. It’s important to stay as calm and relaxed as possible during the test to help ensure the procedure goes smoothly. If you have any concerns or a fear of needles, please let us know in advance so we can provide additional support and make the experience as comfortable as possible for you.
Resume normal eating and drinking unless advised otherwise. If you were fasting, you can eat and drink immediately after the test. You can generally return to your regular activities right away. If you experience any discomfort or dizziness, sit down and rest until you feel better. Results are typically available within a few days to a week. We will inform you as soon as they are received.
