Roche Diagnostics currently offers the NT-proBNP test to detect the level of the NT-proBNP peptide as an aid in the diagnosis of congestive heart failure in patients. It also can assess risk stratification in CHF and in acute coronary syndrome. The Elecsys® proBNP immunoassay is approved for use on the Roche Elecsys 1010, Elecsys 2010, and MODULAR ANALYTICS E170 immunoassay analyzers. The American College of Cardiology/American Heart Association practice guidelines recently were updated to include the NT-proBNP test for diagnosis of heart failure and management of heart-failure patients. The guidelines specify that the use of proBNP be recommended in the evaluation of patients presenting within the emergency care setting when heart failure is suspected.
