Reference ranges apply to patients presenting to the ED setting with acute or worsening dyspnea. For patients in an outpatient setting the test has a very low positive predictive value.In an outpatient setting consider any result <125 pg/mL as negative. For results ≥125 pg/mL, correlation with at least one sign, symptom, or risk factor can be used to identify patients that will need further cardiac investigation.
