Analytical and diagnostic performance for ATP7B peptides.

Peptide LLOD (pmol/L) LLOQ (pmol/L) Intra-assay CV (%) Inter-assay CV (%) PPV (%) NPV (%) AUC
ATP7B 1056 3.81 71.43 12.9 15.3 96.1 91.3 0.98
ATP7B 887 2.17 7.14 11.0 13.0 98.0 91.5 0.98

LLOD = Lower Limit of Detection, LLOQ = Lower Limit of Quantification, CV = Coefficient of Variation, PPV = Positive Predictive Values, NPV = Negative Predictive Value, AUC = Area Under the Curve.
