NT-proBNP Blood Test
1 Biomarker | Venous Blood Test | UKAS-accredited laboratory
NT-proBNP, a marker released when the heart muscle is under strain. Designed for people investigating breathlessness or monitoring known cardiac strain alongside clinical assessment, this test gives you a clear laboratory result alongside the reference range so you can see exactly where you sit.
Results are typically available within 2 working days from when your sample reaches the laboratory (excluding weekends and bank holidays).
Doctor's comments are optional on individual markers. Add them for £15.00 at checkout, or your result is issued as a laboratory report showing your value alongside the reference range.
A laboratory result is not a diagnosis. If you have urgent or worrying symptoms, contact your GP or call 111. In an emergency call 999.
Frequently asked questions
What does the NT-proBNP Blood Test measure?
This test measures NT-proBNP, a hormone fragment released by the heart muscle when it is under strain or stretched by excess fluid.
Who is this test for?
People experiencing breathlessness, ankle swelling or fatigue on exertion, and those monitoring known heart strain. It is more commonly used in older adults where these symptoms need explanation.
How do I prepare for this test?
- Fasting required 8-12 hours before the test (water only), recommended for glucose and cholesterol/triglyceride accuracy
- Sample timing: between 7:00am and 10:00am
- Stay hydrated; avoid strenuous exercise, heavy meals, and supplements (iron, B12, multivitamins, biotin) for 48 hours prior
- Continue prescribed medications unless otherwise directed
How is the sample collected?
This test requires a venous blood draw, so a finger prick sample is not suitable. You can book at our Livingston clinic, at a partner clinic, or arrange a home visit with one of our nurses.
When will I get my results?
Results are typically available within approximately 3 working days of your sample reaching the laboratory. Every result is reviewed by a doctor before release and delivered securely to your online account. All testing is carried out in a UKAS-accredited laboratory.
