Implication
High-sensitivity cardiac troponin assays allow for precise measurement at very low concentrations, promising earlier diagnostic accuracy for MI and improved triage of ACS patients.
Key Points
- Evaluate the analytical advancements and clinical utility of high-sensitivity cardiac troponin assays for early diagnosis and management of acute myocardial infarction.
- Reviewed analytical detection limits, precision profiles, and clinical applications of contemporary versus high-sensitivity cardiac troponin I and T assays.
- Analyzed assay ability to detect low troponin concentrations (1 to 20 pg/mL) with a coefficient of variation ≤10% at the 99th percentile cutoff.
- High-sensitivity assays measure cardiac troponin concentrations down to 1 to 20 pg/mL (0.001 to 0.020 µg/L) with an analytical coefficient of variation ≤10% at the 99th percentile.
- High-sensitivity platforms reliably quantify baseline troponin levels in almost 100% of healthy individuals, compared to only 10% to 20% detectable with contemporary assays.
