Receiver Operating Characteristics of the conventional, and glycovariant assays. The concentrations of the conventional biomarkers (CA125 IA and CA15‐3 IA), and the signal‐to‐background ratios of the experimental assays were used for classifying the healthy controls (n = 18) and breast cancer patients (n = 16). The 95% confidence interval (CI) is noted in parentheses after each area under the curve (AUC) value. The conventional CA125 and CA15‐3 assay (CA125 IA, CA15‐3 IA) are plotted in addition to the experimental wheat germ agglutinin‐reactive glycovariant assays for CA125 (CA125^WGA) and CA15‐3 (CA15‐3WGA), and the experimental CD63 immunoassay (CD63 IA)
