Test Description
The ProBNP test measures the amount of the NT-proBNP prohormone in the bloodstream. Higher levels of NT-proBNP can indicate that the heart is working harder than normal to pump blood, which may be a sign of heart failure[1].
Indications of the Test
The ProBNP test is performed when a person shows symptoms of heart failure, such as shortness of breath and swelling in the legs or abdomen. It is used to evaluate the heart’s ability to pump blood and to differentiate between heart failure and other conditions with similar symptoms[2].
Patient Preparation/Instructions
There is no specific preparation required for the ProBNP test. A blood sample is taken from a vein, usually in the emergency room or hospital. The test is most often done in the emergency room or hospital, and results take up to 15 minutes. Some hospitals offer a finger prick test with rapid results[2].
Typical Reference Values
Normal ProBNP levels are generally considered to be less than 300 picograms/milliliter (pg/mL). However, normal value ranges may vary slightly among different laboratories[5].
Turn Around Time
The turn around time for the ProBNP test is typically up to 15 minutes[2].
