What are the optimal decision limits for ACS:Systems Cardiac Troponin I in patients with acute coronary syndromes?
The ACS:Systems Cardiac Troponin I assay has an optimal decision limit of 3.1 microg/l for acute myocardial infarction and 0.2 microg/l for minimal myocardial damage.

May inform troponin cutoffs for AMI diagnosis; leaves open prospective validation before clinical adoption.
The availability of specific markers of myocardial damage has focused attention on the decision limits to be used in clinical practice. These markers can be employed in the diagnosis of myocardial infarction and risk stratification in patients with acute coronary syndromes but no infarction. The measurement of troponin I was undertaken in two 60 patient cohorts with these disease classifications. The best decision level for patients with acute myocardial infarction was found to be 3.1 microg/l; for the detection of minimal myocardial damage the cut-off was equal to the detection limit of the method (0.2 microg/l).
