Yes, Chronic Kidney Disease (CKD) can be detected through the routine NHS Health Check. This free assessment, offered to adults in England aged 40 to 74 every five years, is specifically designed to spot early warning signs of kidney disease, alongside heart disease, stroke, type 2 diabetes, and dementia. Because CKD often has no noticeable symptoms in its early stages, these routine checks are vital for identifying the condition before significant damage occurs.
The NHS Health Check acts as a “service and MOT” for the body, focusing on the major preventable conditions that become more common as we age. Kidney disease is often called a ‘silent’ condition because you can lose up to 90% of your kidney function without feeling unwell. By the time symptoms like swelling or fatigue appear, the disease is often advanced. The routine check uses simple, evidence-based tests to measure how well your kidneys are filtering waste, allowing for early intervention that can slow or even stop the progression of the disease. This article explains how the check works, who is eligible, and what happens if a potential kidney issue is found.
What We Will Discuss in This Article
- Eligibility for the free NHS Health Check.
- The specific tests used to assess kidney function (eGFR and ACR).
- How high blood pressure and cholesterol tests relate to kidney health.
- What happens during and after the assessment.
- The importance of the ‘5-year’ check-up cycle.
- Identifying “high-risk” groups who may need more frequent testing.
- Practical lifestyle advice given during the check to protect your kidneys.
How the NHS Health Check Detects CKD
The NHS Health Check involves two main parts: a series of questions about your lifestyle and a set of straightforward clinical tests. To assess your kidney health, the healthcare professional usually a nurse or healthcare assistant will perform or review the following:
- Blood Pressure Check: High blood pressure is both a cause and a symptom of kidney disease. If your reading is consistently high, it triggers further investigation into your kidney function.
- Blood Test: You will have a blood sample taken to check your estimated Glomerular Filtration Rate (eGFR). This test measures the level of creatinine (a waste product) in your blood to see how effectively your kidneys are filtering.
- Urine Test (if required): If you have high blood pressure or diabetes, you may be asked to provide a urine sample for an Albumin:Creatinine Ratio (ACR) test. This checks for protein leakage, which is an early sign of kidney damage.
- eGFR Test: Estimates your kidney’s “percentage” of function.
- ACR Test: Detects physical damage to the kidney’s filters.
- Blood Sugar Test: Checks for diabetes, the leading cause of CKD in the UK.
Eligibility and the 40–74 Age Range
The NHS Health Check is offered to people who do not already have a pre-existing condition. If you have already been diagnosed with CKD, heart disease, or diabetes, you should not have an NHS Health Check; instead, you should be receiving annual reviews specifically for your condition.
| Group | Status | Monitoring Frequency |
| Aged 40–74 (Healthy) | Eligible for NHS Health Check | Every 5 years |
| Aged 40–74 (with CKD) | Not eligible for the ‘Check’ | Annual Clinical Review |
| Aged under 40 | Only if at high risk | As advised by GP |
| Aged over 74 | Not automatically invited | Can request advice from GP |
What Happens After the Check?
Once your results are ready, your healthcare professional will discuss your individual risk level with you. If the tests suggest your kidneys aren’t working as well as they should, you won’t necessarily be diagnosed with CKD immediately.
Because kidney function can fluctuate, a single “low” eGFR result must be confirmed with a second test, usually three months later. This ensures the drop wasn’t caused by a temporary issue like a recent infection or dehydration. If CKD is confirmed, you will be given advice on how to manage it, which often includes:
- Blood Pressure Targets: Aiming for a lower reading to protect your filters.
- Medication Review: Checking if you should start “renoprotective” drugs like ACE inhibitors.
- Lifestyle Changes: Help with quitting smoking, losing weight, or reducing salt intake.
Differentiation: Routine Check vs. Symptomatic Testing
It is important to understand that the NHS Health Check is for people who feel fine. If you already have symptoms that concern you, you should not wait for an invitation for a routine check.
- Routine Check: For those with no symptoms; designed for early detection.
- Symptomatic Testing: If you have swollen ankles, changes in urination, or blood in your urine, your GP will perform specific diagnostic tests immediately, regardless of your age or when your last “Health Check” was.
To Summarise
The NHS Health Check is a powerful tool for the early detection of Chronic Kidney Disease in the UK. By screening adults aged 40 to 74 every five years, the programme identifies thousands of cases of “silent” kidney damage that would otherwise go unnoticed. Through simple blood and blood pressure tests, the check allows for early lifestyle and medical interventions that can preserve kidney function and reduce the risk of future complications like heart attacks and strokes. If you are eligible, attending your check is one of the most effective ways to protect your long-term renal health.
If you experience severe, sudden, or worsening symptoms, call 999 immediately.
How do I get an NHS Health Check?
In England, you will usually be sent an invitation letter from your GP surgery or local council every five years. If you think you are eligible and haven’t had one, you can contact your GP.
Can I get a kidney check if I am under 40?
The routine NHS Health Check is for those over 40. However, if you have a family history of kidney disease, have diabetes, or are of South Asian or Black origin, your GP may screen you earlier.
Is the blood test for the health check fasting?
In some areas, you may be asked to fast (not eat) for several hours before the blood test to ensure the cholesterol and glucose readings are accurate, but this varies by clinic.
Does a ‘normal’ result mean I won’t get kidney disease in the next 5 years?
It means your risk is currently low, but lifestyle factors can change. That is why the check is repeated every five years.
Can the check detect kidney stones?
No, the NHS Health Check is designed to measure filtration and long-term function. Kidney stones are usually diagnosed via symptoms and imaging like an ultrasound.
