Analytical Issues Surrounding Troponin Assays
How Sensitive Does Troponin Testing Really Need to Be?
October 2010
How sensitive does troponin testing really need to be at this point? Essentially troponin assays need to diagnose patients with AMI as early as possible and identify patients are risk of premature death from cardiovascular disease. To do this as accurately as possible the assays require an acceptable precision within the normal range.
