NT-proBNP

The N-Terminal Pro B-Type Natriuretic Peptide (NT-proBNP) test measures the level of NT-proBNP, a peptide released by the heart in response to increased pressure and volume. This test is primarily used to diagnose and manage heart failure, as elevated NT-proBNP levels are indicative of heart stress and dysfunction.

Sample type:

Serum

Preparation:

You do not need to do anything special to prepare for the sample collection. Fasting is not required for this test.

Test type:

In person or via trained mobile phlebotomist

Biomarkers

Symptoms or conditions analyzed by this test

The NT-proBNP test is used to evaluate heart function and diagnose heart failure. Elevated NT-proBNP levels can indicate heart failure, characterized by symptoms such as shortness of breath, fatigue, and swelling in the legs or abdomen. The test helps differentiate heart failure from other respiratory or cardiac conditions, assess the severity of heart failure, and guide treatment strategies. Monitoring NT-proBNP levels can also track the effectiveness of treatment and disease progression.
