Preparing for High-Sensitivity Cardiac Troponin Assays
Preparing for High-Sensitivity Cardiac Troponin Assays
Routine use of hs-cTn assays in the United States is inevitable. These assays hold the promise of improving the sensitivity of AMI diagnoses, shortening the duration of AMI evaluation and improving the risk stratification of other noncardiac diagnoses. However, to be able to fully realize their potential, additional studies are needed to address the knowledge gaps we have identified. In the interim, clinicians need to learn how to use the 99% URL and the concept of changing values so when the day comes that hs-cTn assays are available, they will have experience with the important basic concepts.
