Triage BNP Test TRIAGE BNP TEST
Introducing a rapid, objective point-of-care test to aid in the diagnosis of CHF*.

The Triage® BNP Test is the first objective measurement for CHF.

  • Blood test measuring B-type natriuretic peptide (BNP)
    • Cardiac hormone produced by the heart ventricles in response to ventricular volume expansion and pressure overload1
    • Excellent hormonal marker of ventricular systolic and diastolic dysfunction2

The Triage® BNP Test provides meaningful diagnostic information not available from other clinical assessments:

  • 98.0% diagnostic accuracy in initial studies versus all other clinical findings in patients with or without disease history3
  • Quantitative and accurate point-of-care results help differentiate nonspecific signs and symptoms (dyspnea)3 with results in approximately 15 minutes
  • 98.0% specificity using a 100 pg/mL cutoff4
  • >98.0% NPV utilizing 100 pg/mL cutoff4†
  • Corrected 96.0% of misdiagnoses of patients with suspected CHF in initial studies3
  • Diagnostic accuracy confirmed for:
    • Early- and late-stage CHF in point-of-care setting3
    • Patients with normal and abnormal ejection fractions4
  • Initial studies indicate that BNP is predictive of systolic and diastolic LVD3
  • BNP levels are not influenced by hypertension, diabetes, renal insufficiency, or COPD4




* The Triage® BNP Test is indicated for use as an aid in the diagnosis of congestive heart failure.
† Negative predictive value (NPV) was calculated to reflect the incidence of CHF, according to data from the American Heart Association 2000 Heart and Stroke Statistical Update and Health, United States, 2000 (National Center for Health Statistics).
