What biomarkers do you test for celiac disease screening and monitoring?

We test using the same biomarkers that your doctor would test for if you asked for a celiac disease screening test. We test for several biomarkers that can help paint an overall risk assessment for celiac disease. We test for tTg IgA (95% sensitivity and 99% specificity), tTG IgG (88% sensitivity 96% specificity), DGP IgA (81% sensitivity and 93% specificity), and DGP IgG (82% sensitivity and 92% specificity).
