Template:BNP value
Brain natriuretic peptide (BNP)
- <100 CHF ruled out (Sn 90%, NPV 89%)
- 100-500: Consider differential diagnosis and pre-test probability
- > 500 Positive (CHF Sp 87%, PPV 90%)
Differential Diagnosis (Elevated BNP)
May have false negatives with obesity and diastolic dysfunction
Utility
- Obtaining BNP value may not add anything to patient centered outcomes[1]
- May be used to gauge treatment response in acute decompensated CHF
