Interpretation of cardiac troponin values

Troponin valueCommentInterpretation
Below detection limit of the assayUndetectable by assay method usedNo myocardial necrosis found
Between detection limit and functional sensitivity (%CV of 10)Troponin present and can be distinguished from background but cannot be quantified repeatably at this levelPossible myocardial injury. In the context of suspected ACS, repeat after 6 hours and investigate
Above functional sensitivityDefinite myocardial necrosis, measurements are repeatableAMI when seen in the context of suspected ACS
