hsTnI 99th percentile URLs (ng/L), CV% at the URL, and proportion (%) of measurable samples above the LoD for both assays

Assay hsTnI 99th percentile URL (ng/L) LoD (ng/L) % Measurable Assay designation

Men (CV%) Women (CV%) All (CV%)
Centaur hsTnI 15.3 (5.1%) 11.9 (5.3%) 13.5 (5.2%) 2.2 91.5 Level 3 (second generation, high sensitivity)
Atellica hsTnI 15.5 (3.4%) 12.9 (3.5%) 13.4 (3.5%) 1.3 93.4 Level 3 (second generation, high sensitivity)

URLs were determined based on AACC and AFCC guidelines. Assay designation was performed according to the proportion (%) of measurable samples (Apple, 2009 [30]).

Abbreviations: URL, upper reference limit; LoD, limit of detection; AACC, American Association for Clinical Chemistry; IFCC, International Federation of Clinical Chemistry; hsTnI, high-sensitivity troponin I.
