[Relation between intermediate troponin T values and diagnosis of cardiac disease].

Background And Objective: Troponins are useful tools in management of patients with acute coronary syndrome (ACS). Small increases do not guarantee a desirable precision (CV < 10%) and there is a "grey zone" between 99 percentile and clinical cut off. Our objective was to evaluate if "grey zone" troponin values reflect heart damage or they are only "analyzer noise".
