Test Name: BNP (B-Type Natriuretic Peptide)

About:
The BNP test measures the level of B-Type Natriuretic Peptide, a hormone released by the heart when it is under stress or strain. It is one of the most important tests for diagnosing and monitoring heart failure.

Test Overview:
High BNP levels indicate that the heart is working harder than normal to pump blood. This test helps differentiate heart failure from other causes of breathlessness or fatigue.

Reports Delivery:
Usually available within a few hours.

Is Fasting Required:
No

Description

Number of Tests Included:
Single blood test measuring BNP levels.

What is a BNP Test?
A BNP test determines the level of natriuretic peptides released from the heart. When the heart chambers stretch due to pressure or volume overload, BNP levels rise, making it a valuable cardiac marker.

Purpose of the Test:

  • Diagnose heart failure

  • Evaluate severity of heart failure

  • Distinguish heart-related breathlessness from lung disorders

  • Monitor treatment response in cardiac patients

  • Detect worsening heart function

Who Should Get This Test?

  • People with symptoms like shortness of breath, fatigue, swelling in legs, or chest discomfort

  • Individuals with known cardiac conditions

  • Patients being monitored for heart failure

  • Individuals with uncontrolled hypertension

Components of the Test:

  • Serum BNP level measurement

Understanding the Test Report:

  • High BNP → Suggestive of heart failure, cardiac stress, or volume overload

  • Normal/Low BNP → Heart failure is unlikely; symptoms may be due to respiratory or other non-cardiac causes

  • Levels correlate with severity of heart dysfunction.

Preparation and Procedure:

  • No special preparation required

  • Routine blood sample collection

How is the Test Done?
A blood sample is analyzed using high-sensitivity immunoassay techniques to measure BNP concentration.

Best Time for Test:
Anytime when symptoms of heart strain appear or as advised by your cardiologist.
