Celiac disease(CD)affects at least 1%of the Western population but remains largely *** our laboratory,we utilize a novel algorithm to diagnose pediatric CD that offers both high sensitivity and high specificity for diagnosis in an outpatient *** aim of the present study was to challenge this algorithm and to test its performance in children and adults suspected of having *** a three-assay algorithm,screening with the most sensitive tissue transglutaminase(tTG)complexed with deamidated gliadin peptide neoepitope immunoglobulin A(IgA)1IgG assay and confirming with the two specific tTG IgA and tTG IgA1IgG assays,we examined the serological results from 112 children aged 0–17 years old and 60 adults in comparison to their respective biopsy *** algorithm performance was calculated by statistical *** use of the new algorithm enabled us to diagnose CD with 98%sensitivity,93%specificity and 95%accuracy in the pediatric group and 94%sensitivity,92%specificity and 93%accuracy in the total population *** false-negative cases in the adult group were attributed to previous adherence to a gluten-free diet,and the single false-negative result in a young child became a true positive after 6 *** have also monitored three celiac patients before and after diagnosis and found that the algorithm may be suitable for disease *** newly proposed three-assay algorithm for celiac detection is very reliable in both children and *** to the high performance of this assay,the further need for confirmatory intestinal biopsies will be reassessed.
