تست Pro BNP

A number of studies support a decision threshold for NT-proBNP of 125 pg.ml in non-acute onset for the diagnosis of heart failure.
NT-proBNP values < 125 pg.ml exclude cardiac dysfunction with a high level of certainty in patients with symptoms suggestive of heart failure e.g. dyspnea.
NT-proBNP have a very high negative predictive value (NPV) comprised between 94 % and 98.0 % and a positive predictive value (PPV) comprised between 44% and 57 %.
please refer to attached reference interval table (based on age).
For diagnostic purposes, the results should always be assessed in conjunction with the patient s medical history , clinical examination and other findings.
