Clinical Significance
If patient's result is : < 99th percential:
If patient result is > 99th percential:
High Sensitivity Troponin result is at or below the 99th percentile upper reference limit. Myocardial injury is unlikely. Recommend additional and serial testing to exclude evolving myocardial injury or acute coronary syndrome as clinically indicated
If patient result is > 99th percential:
High Sensitivity Troponin result exceeds the 99th percentile upper reference limit. This is consistent with myocardial injury. Causes include but are not limited to: heart failure, myocarditis, sepsis, chronic kidney disease, PE). Recommend additional and serial testing to determine if stable hs-Troponin elevations are present consistent with chronic myocardial injury.
Rising and/or falling levels in the absence of ischemia, suggest acute myocardial injury.
Rising and/or falling levels in the presence of ischemia and the appropriate clinical setting are consistent with an acute myocardial infarction
