N-terminal atrial natriuretic peptide precursor (NT proBNP) is a peptide hormone secreted by the heart. It is an important regulator of heart failure and physiology. The recommendations of ACC / AHA, European Heart Association (ESC) and guidelines for the diagnosis and treatment of heart failure are of high value for diagnosis and prognosis evaluation.
Detection range | sample size | Sample type | Test time |
80~20000pg/mL | 60μl | Whole blood / serum / plasma | 15min |
Acute heart failure | ||
Age | NT-proBNP(pg/ml) | Diagnosis of heart failure |
There is no age limit | <300 | Preclude heart failure |
< 50 years old | 300-450 | Heart failure is unlikely to be diagnosed with other clinical symptoms. |
50-75 years old | ≧450 | High risk of heart failure |
300-900 | Heart failure is unlikely to be diagnosed with other clinical symptoms. | |
≧900 | High risk of heart failure | |
>75 years old | 300-1800 | Heart failure is unlikely to be diagnosed with other clinical symptoms. |
≧1800 | High risk of heart failure | |
Chronic heart failure | ||
There is no age limit | <400 | Elimination of heart failure |
400- 2000 | Multi index differential diagnosis should integrate clinical symptoms, ECG, chest film and cardiac ultrasound. | |
≧2000 | Heart failure is a high risk. |
