The current accepted approach is aggressive case finding with vigilance for the many potential manifestations of coeliac disease and a low threshold for serological testing. Perhaps the group of most concern is young children with a first-degree relative with coeliac disease, as the approximate 7% risk of coeliac disease is considerable and delayed diagnosis has the potential to lead to a permanent loss in growth potential. For this reason, serological testing may be considered before the onset of symptoms in at-risk children. Well-designed, randomised clinical trials do not suggest that either breastfeeding or timing of gluten introduction into the diet alter the risk of coeliac disease in children with a family history of coeliac disease.[93][94][95]
