Establishing the 99 percentile for high sensitivity cardiac troponin I in healthy blood donors from Southern Italy.

Introduction: The knowledge of high sensitivity cardiac troponin I (hsTnI) distribution in a reference population is mandatory for its introduction in clinical practice. The aim of this study was to define the Upper Reference Limit (URL) of hsTnI measured by Single Molecule Counting technology (SMC) in an accurately selected reference population.

Materials And Methods: In the study 1140 blood donors were included and selected on the basis of medical history and biomarkers.

Establishing the upper reference limit of Galectin-3 in healthy blood donors.

Introduction: Galectin-3 (Gal-3) is an independent predictor of poor outcomes and mortality in patients with heart failure (HF). Thus, it has been proposed as a reliable prognostic biomarker for HF. The definition of reference intervals is mandatory for interpreting the findings of experimental studies and encouraging the routine use of biomarkers in clinical practice.
