Overview of the Brain Natriuretic Peptide (NT-pro BNP)
The Brain Natriuretic Peptide (NT-pro BNP) blood test measures N-terminal pro-B-type natriuretic peptide, usually abbreviated to NT-proBNP.
Despite the historic use of the word "brain" in the name, NT-proBNP is primarily released in relation to cardiac ventricular wall stress.
When heart muscle is stretched because of increased pressure or volume, proBNP is released and divided into active BNP and the inactive NT-proBNP fragment.
The test contains 1 biomarker: BNP (NT-pro BNP).
NT-proBNP is widely used to support the investigation of suspected heart failure, particularly in people presenting with unexplained breathlessness.
A low concentration can make clinically significant heart failure less likely, while increased concentrations can indicate greater cardiac wall stress and may lead to echocardiography and specialist assessment.
NT-proBNP is not specific to heart failure. Levels can also increase with age, reduced kidney function, atrial fibrillation, pulmonary hypertension and other cardiovascular or systemic conditions.
Conversely, obesity and several heart-failure medicines can reduce NT-proBNP concentrations.
The result should therefore be interpreted alongside symptoms, examination findings, ECG, kidney function and cardiac imaging where appropriate.
What Does the Brain Natriuretic Peptide (NT-pro BNP) Test Check?
This test measures 1 biomarker.
BNP (NT-pro BNP)
Measures N-terminal pro-B-type natriuretic peptide, which is released in response to increased pressure and stretching of the heart muscle. It is commonly used to support investigation and monitoring of heart failure.
Who May Benefit From the Brain Natriuretic Peptide (NT-pro BNP) Test?
This test may be suitable for people with symptoms suggestive of heart failure or for selected patients undergoing monitoring of known cardiac dysfunction.
People with unexplained breathlessness - NT-proBNP can help assess whether cardiac dysfunction may be contributing to shortness of breath.
People with ankle or leg swelling - Peripheral oedema can occur in heart failure but also has many other causes.
People with reduced exercise tolerance - Increasing difficulty performing usual physical activity may warrant cardiovascular assessment.
People who become breathless when lying flat - Orthopnoea can occur when fluid congestion is associated with heart failure.
People waking at night feeling breathless - Paroxysmal nocturnal dyspnoea can prompt investigation of cardiac function.
People with suspected heart failure - NT-proBNP is widely used as part of the diagnostic pathway before specialist echocardiography.
People with established heart failure - Repeat measurements may occasionally contribute to monitoring alongside symptoms and other cardiac investigations.
People with unexplained fluid retention - Rapid weight gain or swelling may lead to assessment of possible cardiac causes.
Specialist-requested cardiac testing - The test can be arranged privately where a cardiologist or GP has specifically requested NT-proBNP.
How to Prepare
Do not stop diuretics, ACE inhibitors, ARBs, beta blockers or other prescribed cardiac medication simply to alter the result.
NT-proBNP is most useful when interpreted together with symptoms, age, kidney function, body composition and cardiac imaging.
Symptoms and Reasons to Consider the Brain Natriuretic Peptide (NT-pro BNP) Test
You may wish to consider the Brain Natriuretic Peptide (NT-pro BNP) test if symptoms raise concern about cardiac strain or heart failure.
Shortness of breath - Breathlessness during activity or at rest is a common reason for NT-proBNP testing.
Swelling of the ankles or legs - Fluid retention can occur when cardiac pumping function is impaired.
Reduced exercise tolerance - Becoming unusually breathless or fatigued during routine activities can warrant cardiovascular evaluation.
Breathlessness when lying flat - Needing additional pillows or preferring to sleep upright may occur with pulmonary congestion.
Waking suddenly at night short of breath - This can occur in heart failure and requires clinical assessment.
Rapid unexplained weight gain - Increasing weight over a short period can reflect fluid retention.
Persistent fatigue - Reduced cardiac output can contribute to tiredness, although fatigue is highly non-specific.
Persistent cough or wheezing with fluid-retention symptoms - Cardiac congestion can occasionally mimic respiratory disease.
These symptoms can occur with many cardiac, respiratory, renal and systemic conditions.
NT-proBNP supports clinical assessment but does not diagnose heart failure by itself. Echocardiography is usually required to assess cardiac structure and function where heart failure is suspected.
Severe breathlessness at rest, chest pain, collapse, blue lips, marked confusion or rapidly worsening symptoms require urgent medical assessment.
How to Book Your Brain Natriuretic Peptide (NT-pro BNP) Test
Booking your Brain Natriuretic Peptide (NT-pro BNP) test with London Blood Tests is simple and designed to fit around your schedule.
Choose the Brain Natriuretic Peptide (NT-pro BNP)
Select the NT-proBNP test online and review the included cardiac biomarker before booking.
Select your sample collection option
Choose an in-clinic blood draw (+£35) or a home or hotel phlebotomy visit (+£60) where a qualified phlebotomist collects your sample.
Attend your appointment
A trained professional will collect the required venous blood sample.
Laboratory analysis
Your sample is sent to the laboratory, where BNP (NT-pro BNP) is measured using specialist cardiac biomarker analysis.
Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, cardiologist or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the Brain Natriuretic Peptide (NT-pro BNP) test is approximately 1 business day after your sample arrives at the laboratory.
Results are sent securely once laboratory analysis and authorisation are complete.
Additional laboratory checks may occasionally extend reporting time.
Understanding Your Results
A lower NT-proBNP result makes significant heart failure less likely, particularly when assessed within established diagnostic pathways.
For suspected chronic heart failure, UK referral pathways commonly use NT-proBNP thresholds to guide further assessment.
Values below 400 ng/L generally make heart failure less likely in an untreated person, although clinical judgement remains important.
Values between approximately 400 and 2,000 ng/L generally support referral for specialist heart-failure assessment and echocardiography.
Values above approximately 2,000 ng/L are associated with a higher likelihood of heart failure and usually warrant more urgent specialist assessment.
These thresholds are clinical pathway values rather than universal laboratory reference ranges.
NT-proBNP can be increased by age, renal impairment, atrial fibrillation and other cardiac conditions.
Obesity and several heart-failure medicines may reduce concentrations.
The result should therefore be interpreted alongside symptoms, examination, ECG, kidney function and echocardiography.
