Analytical and clinical performance of the Ortho-Clinical Diagnostics VITROS amino-terminal pro-B type natriuretic peptide assay.

Background: Measurement of amino-terminal pro-B-type natriuretic peptide (NT-proBNP) is useful for evaluating patients with heart failure (HF).

Methods: We evaluated the performance of a new automated NT-proBNP assay.

Results: The VITROS NT-proBNP assay had mean within-run and total imprecision of 1.
