  • Abnormal values were those exceeding the 90th percentile for healthy controls for AOPPs, %HAA, and Gd-IgA1, and those lower than 10th percentile for healthy controls for SH-Alb. AOPPs, advanced oxidation protein products; Gd-IgA1, galactose-deficient IgA1; %HAA, % Helix aspersa agglutinin; SH-Alb, free sulfhydryl groups on albumin.
