NT-proBNP blood test in Chiswick
A blood test for NT-proBNP, a marker released when the heart muscle is under strain, used by doctors when heart failure is being considered and for following up heart questions with your practitioner.
What the test measures
NT-proBNP (N-terminal pro B-type natriuretic peptide) is released by the heart, mainly from the ventricles, when the heart muscle is stretched or working harder than usual. In the NHS it is used, following NICE guidance, to help decide whether someone with possible heart failure needs an urgent heart scan (echocardiogram) and specialist review.
Levels are influenced by more than the heart. NT-proBNP rises with age and is often higher in people with reduced kidney function or atrial fibrillation, and it can be lower in people living with obesity. A result is therefore always interpreted in context.
The price includes the sample taken at our Chiswick clinic, analysis at the Randox accredited laboratory, a practitioner review of your result, and a GP feedback report on request.
Who it is for
- You have ankle swelling, tiredness or reduced exercise tolerance and want to discuss heart strain with your practitioner.
- You have a known heart condition and your doctor would like an NT-proBNP level.
- You have high blood pressure or diabetes and want a broader picture of heart health.
- You would like a result to share with your GP as part of an ongoing heart review.
- You understand this test does not replace emergency care for sudden symptoms.
Understanding your result
Your report shows your NT-proBNP level alongside the laboratory reference range. NICE uses age-related thresholds, and a raised level suggests the heart may be under strain and that further assessment, such as an echocardiogram, is worth discussing with your GP. A low level makes heart failure less likely but does not exclude other heart conditions.
Your practitioner will read the result together with your symptoms, age, kidney function and medicines. A result outside the range is a prompt for discussion, not a diagnosis.
Preparing for your test
No fasting is needed and you should take your usual medicines unless your doctor has told you otherwise. Please note that this is not an emergency test. If you have chest pain, sudden or severe breathlessness, or symptoms of a clot such as a painful swollen leg, call 999 or go to A&E rather than booking a test.
Heart strain is often looked at alongside cholesterol and kidney health. Our cholesterol tests and kidney function tests can add context. You can also see every blood test and price in Chiswick.
Questions
How much is an NT-proBNP test in Chiswick?
The NT-proBNP (Heart Strain) test is £129. It includes the blood sample at our Chiswick clinic, analysis at the Randox accredited laboratory, a practitioner review of your result, and a GP feedback report on request.
What does a high NT-proBNP mean?
It can mean the heart is under strain, but levels also rise with age, kidney problems and atrial fibrillation. Your GP may recommend a heart scan to find out more.
Can NT-proBNP diagnose heart failure?
Not on its own. It helps doctors decide who needs further tests, and a diagnosis is made with an echocardiogram and clinical assessment.
Should I book this test if I have chest pain?
No. Chest pain or sudden breathlessness needs urgent care. Call 999 or go to A&E.
