Reference Range

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.
