Analytical Issues Surrounding Troponin Assays
Why All the Hype for High-Sensitivity Troponin?

October 2010
What is all the hype about high-sensitive troponin assays? While there are no FDA-approved high-sensitive assays, there are many in development and being used for research use only. Their use has been shown to diagnose MI earlier, greater prediction of death or future MI, and an improvement in risk stratification. It should be noted that the improvement in sensitivity is at the expense of specificity.
