The AQT90 FLEX B-type Natriuretic Peptide (BNP) and N-terminal pro B-type natriuretic peptide (NT-proBNP) Tests are in vitro diagnostic assays intended as an aid in the diagnosis and assessment of the severity of heart failure in point-of-care and laboratory settings. The purpose of the study is to establish the clinical performance of the AQT90 FLEX BNP and NT-proBNP assays for both whole blood and plasma in the intended use population.

Primary Outcome Measures:
  • Determination of the clinical sensitivity and specificity of the AQT90 FLEX BNP and NT-proBNP assays at the clinical cut-off in heart failure patients [ Time Frame: Single blood draw upon study entry ] [ Designated as safety issue: No ]
    Clinical sensitivity and specificity with 95 % confidence intervals of the AQT90 FLEX BNP and NT-proBNP assays will be determined at the clinical cut-off in heart failure patients divided by age, gender and New York Heart Association (NYHA) functional classification.
