Helping to identify the severity of congestive heart failure and risk stratification of acute coronary syndrome

Contact Us

The Stratus® CS Acute Care™ NT-proBNP assay is an in vitro diagnostic test for the quantitative measurement of N-terminal pro-brain natriuretic peptide (NT-proBNP) in heparinized plasma. In individuals suspected of having CHF, measurements of NT-proBNP are used as an aid in diagnosis and the assessment of severity. The test is further indicated for the risk stratification of patients with acute coronary syndrome and heart failure, resulting from left-ventricular dysfunction.



Features & Benefits

  • One sample, one run, one instrument; increases efficiency in triaging chest pain patients
  • Rapid turnaround time - in as little as 14 minutes (with onboard centrifugation)
  • Single and ready to use TestPak™ Cartridges
             o No reconstitution

  • Heparinized whole blood samples
  • Electronic QC (System Check) satisfies daily routine QC requirements permitting liquid QC flexibility 


Clinical Use

Measurements of NT-proBNP are used as an aid in the diagnosis of individuals suspected of having congestive heart failure (CHF). Other potential clinical uses of NT-proBNP are risk stratification of patients with acute coronary syndrome (ACS) and CHF, as well as treatment and monitoring in patients with left ventricular dysfunction (LVD).
