Popis: This study determined whether, for patient monitoring, it is feasible to convert B-type natriuretic peptide (BNP) results obtained using Triage (BNP, Biosite, San Diego, CA), Centaur (BNP, Bayer Diagnostics, Tarrytown, NY), and Elecsys 2010 (Nterminal proBNP; Roche, Indianapolis, IN) assays. Concordance between assays and effects of renal impairment also were assessed. Samples were primarily from emergency center patients. Biosite testing was performed immediately; Bayer and Roche testing was performed later on plasma stored frozen (–30°C). Logistic regression relationships were as follows: Bayer = 0.57 Biosite + 23.1, n = 121, R 2 = 0.85; Roche = 6.09 Biosite – 220.4 + 1,131.6 (if female), n = 131, R 2
