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.
