What is a good NT-proBNP level?
A normal level of NT-proBNP, based on Cleveland Clinic’s Reference Range is: Less than 125 pg/mL for patients aged 0-74 years. Less than 450 pg/mL for patients aged 75-99 years.
What is abnormal NT-proBNP?
An abnormal NT-proBNP concentration is an accurate diagnostic test both for the exclusion of HF in the population and in ruling out LVD in breathless subjects. An elevated NT-proBNP merely indicates the presence of ‘cardio-renal distress’ and should prompt referral for further investigation.
How high can NT-proBNP go?
1. Myocardial Stress/Injury
| Cut-off Value | ||
|---|---|---|
| Acute Dyspnea | To exclude acute HF | |
| BNP | <30-50 pg/mL | |
| NT-proBNP | <300 pg/mL | |
| To identify acute HF |
What is NT-proBNP a marker of?
Currently, brain natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are widely used as diagnostic biomarkers for heart failure (HF) and cardiac dysfunction in clinical medicine. They are also used as postmortem biomarkers reflecting cardiac function of the deceased before death in forensic medicine.
What does a BNP of 600 mean?
Suspected heart failure – BNP level > 100 pg/mL is suggestive of a diagnosis of symptomatic heart failure, and a BNP > 400 pg/mL is strongly suggestive of congestive heart failure (CHF), although the average BNP level in patients with CHF is greater than 600 pg/mL.
What does a BNP of 300 mean?
BNP Level (pg/mL) Normal. Any. Less than 300. Possible heart failure.
What does a BNP of 500 mean?
A BNP between 100-400 pg/mL may be considered a “gray zone,” and a diagnosis depends on a careful physical examination and additional testing to determine the cause. A BNP greater than 400 pg/mL indicates that heart failure is likely.
What does BNP 400 mean?
