Anti-gliadin peptide IgA (red symbols) and IgG (green symbols) antibodies immunofluorometric assay (IFMA) and anti-tTG antibodies (tTGA) enzyme-linked immunosorbent assay (ELISA) (blue symbols) were analysed in follow-up sera from children at genetic risk for type 1 diabetes (Finnish Diabetes Prediction and Prevention study). Coeliac disease (CD) antibody responses were determined in individuals who eventually developed CD (a), and in healthy individuals transiently positive in tTGA IgA ELISA (b). The arrows indicate the time-point of small intestine biopsy.
