How It Is Done
A health professional uses a needle to take a blood sample, usually from the arm.
Watch How It Feels
When a blood sample is taken, you may feel nothing at all from the needle. Or you might feel a quick sting or pinch.
Risks
There is very little chance of having a problem from this test. When a blood sample is taken, a small bruise may form at the site.
Results
Normal BNP values are higher in women than in men. BNP values normally increase with age. But they may stay within a normal range unless you have heart failure.
Your doctor will discuss your results with you. A normal BNP level means that you probably don't have heart failure. A higher-than-normal BNP level means that you might have heart failure. A very high BNP level means that heart failure is much more likely.
Your doctor will also look at other tests and your physical exam to find out for sure if you have heart failure.
