Troponin testing is an essential component of our diagnostic approach to patients in acute medical care settings. With the advent of high-sensitivity troponin assays, its importance will extend to patients in chronic disease settings. Although elevated troponin levels provide diagnostic information, inform treatment decisions, and influence patient prognosis, proper interpretation of the values is essential. This requires an understanding of the operating characteristics of troponin testing; the likelihood ratios associated with a positive/negative test result and the pre- and post-test probabilities related to individual clinical settings. These principles will become more important as high-sensitivity assays become introduced over the coming years in the United States. This article reviews the important principles of troponin testing focusing in particular on acute settings and is aimed at internal medicine and hospital specialists. Copyright © 2015 Elsevier Inc.
