Yes, if you have risk factors such as diabetes or high blood pressure (hypertension), you should ensure you are receiving regular, comprehensive kidney checks. In the UK, these checks are a standard part of chronic disease management because both conditions are leading causes of kidney damage. Early kidney issues often present no symptoms, so proactive screening is the only way to detect ‘silent’ changes. The NHS provides these reviews to catch markers like protein in the urine early, allowing for treatments that can significantly slow or prevent the progression of kidney disease.
What We’ll Discuss in This Article
- Why diabetes and high blood pressure are the primary risks for kidney health
- The specific tests included in a ‘full kidney check’ (ACR and eGFR)
- How routine monitoring identifies damage before symptoms appear
- The role of the NHS Annual Review and the Quality and Outcomes Framework (QOF)
- How managing your risk factors directly protects your renal filters
- What to do if you haven’t had a check-up in the last twelve months
Why Risk Factors Require Regular Monitoring
The kidneys are filled with millions of delicate blood vessels that act as filters. Diabetes and high blood pressure are systemic conditions, meaning they affect the blood vessels throughout the entire body, but the kidneys are particularly vulnerable.
- Diabetes: High blood sugar acts like a ‘slow-acting toxin’ to the kidney filters (glomeruli), causing them to become scarred and leaky over time.
- High Blood Pressure: Persistent high pressure forces the small vessels in the kidneys to thicken and narrow, reducing the kidneys’ ability to filter waste and keep essential proteins in the blood.
Research indicates that about one in five people with high blood pressure and one in three people with diabetes will develop some form of kidney disease. Because this damage happens gradually and without pain, regular screening is the most effective tool for long-term safety.
What is Included in a Full Kidney Check?
A comprehensive kidney assessment in a UK GP surgery typically involves two main tests that look at different aspects of how your kidneys are working.
The Two Essential Kidney Tests
| Test Name | What it Measures | Why it Matters |
| Urine ACR Test | Albumin-to-Creatinine Ratio | Detects tiny amounts of ‘leaked’ protein in the urine |
| eGFR Blood Test | Estimated Glomerular Filtration Rate | Measures how effectively the kidneys filter waste from the blood |
The Urine ACR is especially important because it can detect ‘microalbuminuria’ the very first sign of kidney stress years before it would show up on a standard dipstick test or cause a drop in your blood filtration rate. According to National Institute for Health and Care Excellence (NICE) guidelines, these two tests should be performed together at least once a year.

The NHS Annual Review Process
If you have a diagnosis of diabetes or hypertension, you should automatically be invited for an annual review. This is part of the NHS Quality and Outcomes Framework (QOF), a system that ensures patients with chronic conditions receive consistent, high-quality care.
During this review, a nurse or GP will:
- Check your Blood Pressure to ensure it is within a safe range.
- Take a Blood Sample to check your kidney function (eGFR) and, if you have diabetes, your long-term sugar levels (HbA1c).
- Request a Urine Sample (ideally the first one of the morning) to perform the ACR test.
- Review your Medications to ensure you are on the best treatments to protect your kidneys.
Differentiation: Routine Screening vs. Symptomatic Testing
There is a difference between the ‘screening’ you receive as a high-risk patient and the ‘diagnostic’ testing done when someone already has symptoms.
| Feature | Routine Screening (Diabetes/BP) | Symptomatic Testing |
| Frequency | Every 12 months (minimum) | When a new symptom occurs |
| Goal | Catch issues before they cause harm | Identify the cause of a current problem |
| Symptoms | Patient usually feels fine | Patient may have foamy urine or swelling |
| Focus | Prevention and stability | Diagnosis and treatment |
To Summarise
If you have diabetes or high blood pressure, you should not wait for symptoms to appear before checking your kidney health. Regular monitoring through the NHS annual review is the most effective way to detect early changes like protein in the urine. By having your eGFR and ACR checked yearly, you and your GP can work together to manage your risk factors and ensure your kidneys remain healthy and functional for the long term.
If you experience severe, sudden, or worsening symptoms, call 999 immediately.
How do I know if I’ve had a kidney check recently?
You can check your medical records via the NHS App or ask your GP surgery if your annual ‘diabetic’ or ‘hypertension’ review is up to date.
What is a ‘good’ eGFR result?
In most healthy adults, an eGFR of 90 or above is considered normal, though this naturally declines slightly as we get older.
Can I have a kidney check if I don’t have diabetes?
If you have high blood pressure, heart disease, or a family history of kidney issues, you are also entitled to regular monitoring.
Why do I need to give a morning urine sample?
The first-morning sample is the most accurate for measuring protein because it hasn’t been affected by your activity levels during the day.
Can my medication affect my kidney test?
Some medications, like ACE inhibitors, are actually prescribed to protect your kidneys and reduce protein in the urine.
What should I do if my GP hasn’t invited me for a check?
If it has been more than a year since your last review, you should contact your surgery to book an appointment.
Does a high protein diet affect these tests?
Extremely high protein intake can sometimes affect creatinine levels in the blood, so it’s helpful to mention your diet to the nurse.

This article was reviewed by Dr. Stefan Petrov, a UK-trained physician with experience in chronic disease management and general medicine. The guidance follows the clinical standards set by the NHS and NICE regarding the monitoring of patients with diabetes and hypertension. Our goal is to empower patients with risk factors to proactively engage with their annual kidney checks to preserve their renal health.
