Further study details as provided by Radiometer Medical ApS:

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 ]
    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.
