Cardiac / Muscle
Also known as: Brain natriuretic peptide, NT-pro B-type natriuretic peptide test, N terminal proBNP
If you experience sudden or worsening shortness of breath, severe swelling, chest pain, or extreme fatigue, seek immediate medical attention.
The BNP test checks for a protein in your blood. This protein is called B-type natriuretic peptide. Your heart and blood vessels create this protein. It helps your body remove extra salt and water.
Your doctor orders this test to help find out if you have heart failure. It can also help if you have symptoms like feeling short of breath. The test can also show how serious your heart failure is. It can also check your heart health after a heart attack.
Reference ranges for BNP can vary by lab and may also depend on your age, sex, and other health factors. Your doctor will interpret your results based on these considerations.
