BNP levels go up when the heart cannot pump the way it should. A result greater than 100 pg/mL is abnormal. The higher the number, the more likely heart failure is present and the more severe it is.
What is considered high BNP level?
Normal: Less than 100 pg/mL. High: More than 400 pg/mL. Between 100 to 400 pg/mL requires a doctor’s evaluation.
What is a good BNP result?
Experts agree there is a healthy range for BNP levels. The cut-off point can vary by laboratory, but commonly, this range is less than 100 picograms of BNP per milliliter (pg/ml) of blood. This means that a result of more than 100 pg/ml indicates the possibility of heart failure.

What does a BNP of 1400 mean?
The ROC curve analysis showed that the BNP level of 1,400 pg/mL was the best predictor of events; high levels were associated with lower LVEF (0.23 versus 0.28; p = 0.002) and more severe degree of renal dysfunction (mean urea 92 versus 74.5 mg/dL; p = 0.002).

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 900 mean?
If you have heart failure, the following NT-proBNP levels could mean your heart function is unstable: Higher than 450 pg/mL for patients under age 50. Higher than 900 pg/mL for patients age 50 and older.
What does a BNP of 1200 mean?
Very high or very low BNP levels are helpful diagnostically for these patients. A dyspneic person with a BNP 1200 most likely does have CHF.
What does a BNP of 400 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 a high pro BNP mean?
If your BNP or NT-proBNP levels were higher than normal, it probably means you have heart failure. Usually, the higher the level, the more serious your condition is. If your BNP or NT-proBNP results were normal, it probably means your symptoms are not being caused by heart failure.
What does a BNP of 10000 mean?
A level of NT pro-BNP greater than 10,000 pg/mL has confirmed the diagnosis of heart failure in more than 99% of newly diagnosed cases and in 94% of heart failure cases.
Can BNP be too low?
Conclusions: A subset of patients with confirmed HF or cardiac dysfunction have unexpectedly low BNP levels. Obesity is the strongest correlate of unexpectedly low BNP levels. Our findings support the possible existence of NP deficiency, which may render some individuals more susceptible to volume or pressure overload.
What does a BNP of 3000 mean?
Conclusion. These data suggest that the extreme elevation of NT pro-BNP levels (≥3000 pg/ml) is mainly determined by impaired renal function in elderly patients above 80 years. Extreme NT pro-BNP levels may be useful for assessing the severity of impaired renal function.
What does a BNP of 5000 mean?
The Triage BNP Test diagnostic level to exclude heart failure is BNP100 pg/ml is considered positive and indicative of heart failure. In our study, the minimum BNP value was
Which is better BNP vs proBNP?
The diagnostic performance of BNP and NT‐proBNP is comparable and there is no meaningful difference between them. They reflect haemodynamic myocardial stress independent of the underlying pathology, thus they are not specific for a distinct pathology such as heart failure but for cardiovascular diseases in general.
What is a critical value for BNP?
Critical value : BNP: >400 pg/mL (heart failure likely)
What are the 4 stages of congestive heart failure?
There are four heart failure stages (Stage A, B, C and D). The stages range from “high risk of developing heart failure” to “advanced heart failure.”
Stage C Shortness of breath.Feeling tired (fatigue).Less able to exercise.Weak legs.Waking up to urinate.Swollen feet, ankles, lower legs and abdomen (edema).
Can BNP be elevated without heart failure?
Conclusion. BNP is a strong predictor of death in patients with and without HF. The risk of death associated with elevated BNP levels is similar between patients with and those without HF. These data suggest that increased BNP values in patients without HF are important in clinical practice.
