High Sensitivity Troponins — Translating Research into Practice

Abstract

Troponin is vital in the evaluation of acute coronary syndrome. Decision limits, based on the 99^th percentile upper reference limit derived from a sufficiently large normal reference population, must be determined for each specific troponin method. The new troponins exhibit high-sensitivity performance – assay precision at less than 10% coefficient of variation (at the 99^th percentile upper reference limit) and ability to detect measurable values in healthy subjects. The troponin literature has reached a tipping point necessitating guidance on its use from specialist societies.
