Celiac disease is a chronic and multiorgan autoimmune disease that affects the small bowel in genetically predisposed persons due to the ingestion of gluten.1 It can present a wide range of symptoms such as anemia, vague abdominal symptoms, esophagitis, neuropathy, ataxia, depression, short stature, osteomalacia, and multiple others.1 For the majority of patients, their celiac disease remains undiagnosed.1


Diagnostic guidelines for celiac disease recommend starting lab testing with anti-tissue transglutaminase IgA (tTG IgA) combined with the measurement of total serum IgA.1-3

For special conditions, the determination of IgA and IgG antibodies directed to deamidated gliadin peptides and anti-tissue transglutaminase IgG antibodies are recommended.1-3

Helping reduce endoscopies

The European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) 2019 guidelines for the diagnosis of celiac disease state that if an anti-tissue transglutaminase antibody test result is greater than 10 times the manufacturers upper limit of normal range (ULN), then endoscopy can be avoided in favor of confirmatory endomysial antibody (EMA) testing.2

To demonstrate the validity of the ESPGHAN guidelines to conditionally omit biopsies, a prospective multicenter study was performed.5 In this study, it was demonstrated that with a PPV of 99% at just 2 x ULN (20 EliA U/ml) and a PPV of 100% at just 5 x ULN (50 EliA U/ml), the EliA Celikey IgA test may help reduce endoscopies more than any other automated assay. 5
