Plasma 99th Percentile Reference Limits for Cardiac Troponin and Creatine Kinase MB Mass for Use with European Society of Cardiology/American College of Cardiology Consensus Recommendations

Abstract
Background: The European Society of Cardiology/American College of Cardiology (ESC/ACC) consensus document for definition of myocardial infarction (MI) is predicated on increased cardiac troponin or creatine kinase (CK) MB mass above the 99th percentile reference limit. The purpose of this study was to determine the plasma (heparin) 99th percentile reference limits for the leading in vitro diagnostic cardiac troponin and CKMB mass assays.
