Refer to Interpretive Data.
A cutoff of 100 pg/mL has been demonstrated to provide the maximal combination of sensitivity, specificity, and negative predictive value for contributing to the diagnosis of congestive heart failure (CHF). A BNP value greater than 100 pg/mL is consistent with a diagnosis of CHF in the appropriate clinical setting. False-positive results are more common in females greater than 75 years of age. Blood concentrations of natriuretic peptides may also be elevated in patients with myocardial infarction and in patients who are candidates for or are undergoing renal dialysis.
