The effect of hemolysis on current troponin assays--a confounding preanalytical variable?

The universal definition of myocardial infarction stipulates the detection of an increase and/or decrease in cardiac biomarkers [preferably troponin I (TnI)1 or T (TnT)], with at least 1 value >99th percentile of the upper reference limit, together with evidence of myocardial ischemia (1 ).
