The Acute Care™ cTnl assay on the Stratus® CS Acute Care™ Diagnostic System was the first to the market with a guideline acceptable sensitive Troponin-I assay in 2004 and meets the ESC/ACC Joint Committee recommendations of ≤10% CV at the 99th percentile of normal population. This assay is used for the measurement of cardiac troponin I to aid in the diagnosis of AMI and in the risk stratification of patients with acute coronary syndromes (ACS).

Clinical Use

Cardiac troponin I measurements can be used as an aid in the diagnosis of acute myocardial infarction (AMI). Cardiac troponin I can also be used as an aid in the risk stratification of patients with acute coronary syndromes (ACS) with respect to their relative risk of mortality. Given the impressive levels of myocardial specificity and sensitivity, the ESC/ACC Joint Committee has recognized troponin as the preferred biochemical marker for myocardial damage and redefined acute myocardial infarction (AMI), in part, as a rise and gradual fall of troponin levels.1
