Many people spend years with unexplained fatigue, iron deficiency, gut symptoms, osteoporosis or infertility before the coeliac connection is identified. Complete coeliac serology is the first step in diagnosis. Tissue transglutaminase (tTG) IgA is the primary screening marker, with sensitivity around 95 percent when gluten is in the diet. Deamidated gliadin peptide (DGP) antibodies add sensitivity in seronegative or paediatric cases. Total IgA is essential to check, because one in 400 people have selective IgA deficiency, which will produce a false negative on IgA based coeliac tests and requires IgG testing instead.
