A, Affinity comparison of zinc transporter 8 autoantibody (ZnT8A) between 10 individuals with radiobinding assay (RBA) + electrochemiluminescence (ECL) + and 8 individuals with RBA + ECL– at initial screening, red lines: individuals with RBA + ECL + and blue lines: individuals with RBA + ECL–. B, Longitudinal follow-up of ZnT8A affinity in individuals with RBA + ECL–. C, Longitudinal follow-up of ZnT8A affinity in individuals with RBA + ECL+. Solid lines in B and C represent the screening samples and dotted lines represent samples from the last follow up.
