The B-Type Natriuretic Peptide (BNP) Test is a blood test that measures a hormone released by the heart in response to stress or heart failure. It helps doctors diagnose and manage heart conditions, such as heart failure, by assessing the heart's functioning.
Here are the basic details of the BNP Test.

BNP Test | Normal Range |
---|---|
BNP Levels | Less than 100 pg/mL |
Here is the Interpretation of the BNP Test.
BNP Level (pg/mL) | Interpretation |
---|---|
Less than 100 | Typically considered normal for most individuals. |
100 - 400 | Mildly elevated; may indicate heart stress. |
Above 400 | Significantly elevated; often indicative of heart failure or other cardiac issues. |
Here are the potential causes of high BNP Test levels:
Potential Causes | Explanation |
---|---|
Heart failure | A common cause of significantly elevated BNP levels is heart stress. |
Cardiomyopathy | Conditions that affect heart muscle function. |
Myocardial infarction (heart attack) | Acute damage to the heart muscle. |
Valvular heart disease | Heart valve problems that affect cardiac function. |
Pulmonary hypertension | High blood pressure in the lungs. |
Here are the potential causes of low BNP Test levels:
Potential Causes | Explanation |
---|---|
Normal heart function | Low BNP levels may be expected in individuals with healthy heart function. |
Obesity | Lower BNP levels can be associated with obesity. |
Young age | BNP levels may vary with age, being lower in younger individuals. |
Medications | Certain medications can lower BNP levels. |
Kidney disease | Reduced clearance of BNP by the kidneys in renal dysfunction. |

Summary
Overall, BNP Test plays a key role in diagnosing and managing heart failure, aiding in timely treatment and reducing the risk of heart-related complications. Also check Drlogy Test for detailed information about all medical tests for patients, doctors, scholers and medical students.
Reference
BNP levels vary, but generally, for adults, normal is <100 pg/mL. Age-related norms may range up to 450 pg/mL for those over 70. Always consult a healthcare professional.
The cost of a BNP test varies, averaging $50 to $200 without insurance. Factors like location, lab, and insurance coverage influence the final cost.
