What color tube do you use for BNP?
Collect specimen in a plastic EDTA (lavender-top) tube.
How do you perform a BNP test?
A BNP test is done by drawing blood from a vein in your arm using a hypodermic needle. This process is known as venipuncture. A machine then measures levels of BNP or another heart hormone, called N-terminal-pro BNP (NT-pro-BNP), in the blood sample. The results from the test are usually ready in 15 to 20 minutes.
How do you prepare for a BNP blood test?
You don’t need to do anything to prepare for a BNP test or NT-proBNP test. Your provider will clean your arm and insert a needle. Your provider removes some of your blood through a vein. The needle may pinch or sting.
What is a BNP drawn for?
Brain natriuretic peptide (BNP) test is a blood test that measures levels of a protein called BNP that is made by your heart and blood vessels. BNP levels are higher than normal when you have heart failure.

What blood tests detect heart failure?
Tests for 2 kinds of natriuretic peptides are currently available for the diagnosis of heart failure: BNP (B-type natriuretic peptide) and pro-BNP (N-terminal pro–B-type natriuretic peptide). Blood levels of both of these substances become elevated in patients with congestive heart failure.
How does BNP measure heart failure?
The test measures a hormone called “brain natriuretic peptide.” During heart failure, pressure builds up in the chambers of your heart and creates BNP. When the heart works harder and doesn’t pump blood well, it releases this hormone in large amounts. BNP widens your blood vessels to help improve circulation.
What can falsely elevated BNP?
Answer. Falsely high levels of BNP and NT-proBNP may be seen in females, with advancing age and in the presence of renal failure.
Can dehydration cause elevated BNP?
Furthermore, levels of BNP can remain high even after achieving an adequate hydration status because of a stretched myocardium (i.e., dry BNP), renal failure, liver failure, pulmonary embolus, and acute coronary syndromes [6, 10].
What lab test is BNP?
What is BNP blood test NHS?
BNP is a natriuretic peptide hormone secreted by the left ventricle of the heart. The N-terminal Pro-B-type natriuretic peptide (NTproBNP) is an assay used as an aid in the diagnosis of individuals suspected of having congestive heart failure.
