Currently accepted indications for celiac disease testing are ineffective and fail to discriminate between patients with and without undiagnosed celiac disease, according to a case-control study in Alimentary Pharmacology and Therapeutics. Although almost 40% of a 400-patient cohort had at least one testing indication, the study found that fewer than 5% of the patients were actually tested for celiac disease — suggesting, the authors said, a strong need for alternative methods of detecting symptomatic celiac disease.
