Answer

The authors developed a series of diagnostic algorithms to compare costs and resource utilization. [17] In the most cost-effective one, biopsies are reserved for patients with positive results on composite TG-2/DGP IgA/DGP IgG screening who are confirmed to be genetically susceptible to celiac disease and show abnormalities on confirmatory TG-2 IgA, DGP IgG, or DGP IgA testing. With this model, cost per case diagnosed is reduced by 38% in women and 25% in men, and gastroscopies are reduced by 38% in women and 65% in men. [17]
