Table 9: Natriuretic peptide cut points for the diagnosis of HF
| Acute setting - BNP (Age: All) |
| HF is unlikely |
| < 100 pg/mL |
| HF is possible but other diagnoses need to be considered |
| 100-400 pg/mL |
| HF is very likely |
| > 400 pg/mL |
| Acute setting - NT-proBNP (Age: < 50) |
| HF is unlikely |
| < 300 pg/mL |
| HF is possible but other diagnoses need to be considered |
| 300-450 pg/mL |
| HF is very likely |
| > 450 pg/mL |
| Acute setting - NT-proBNP (Age: 50-75) |
| HF is unlikely |
| < 300 pg/mL |
| HF is possible but other diagnoses need to be considered |
| 450-900 pg/mL |
| HF is very likely |
| > 900 |
| Acute setting - NT-proBNP (Age: > 50) |
| HF is unlikely |
| < 300 pg/mL |
| HF is possible but other diagnoses need to be considered |
| 900-1800 pg/mL |
| HF is very likely |
| > 1800 |
| Ambulatory-care setting - BNP |
| Age, Years |

BNP, B-type natriuretic peptide;
HF, heart failure;
NT-proBNP, N-terminal propeptide B-type natriuretic peptide.
