Implication

This editorial highlights the importance of rigorous analytical validation, appropriate quality control, and evidence-based clinical application of high-sensitivity cardiac troponin assays to ensure patient safety and accurate diagnosis of acute myocardial infarction.

Key Points

To critically evaluate analytical performance specifications, quality control procedures, and clinical reporting standards for high-sensitivity cardiac troponin assays.
Critiqued expert laboratory recommendations concerning calibration thresholds, limit of detection monitoring, and reference population criteria for cardiac troponin (cTn) testing.
Evaluated diagnostic misclassification models and analytical performance specifications derived from clinical outcome studies and simulation data.
Target analytical performance specifications at the 99th percentile upper reference limit require a coefficient of variation <10% and bias within ±10% to restrict false-positive misclassification rates to approximately 1%.
Patients with mildly decreased renal function (estimated glomerular filtration rate 60–90 mL/min/1.73 m²) exhibit 1.21-fold higher high-sensitivity troponin T and 1.14-fold higher troponin I levels, demonstrating that reference populations require stringent health exclusion criteria.
Standardizing reporting units to whole numbers in nanograms per liter (ng/L) rather than micrograms per liter (µg/L) with decimals is essential to minimize medical errors.
