Reference Range

IgA levels are normal and both TTG IgA and EMA IgA levels are within normal limits.

In low risk patients (<5% disease probability), celiac disease is effectively excluded.
In high risk patients (>5% disease probability), small bowel biopsy is recommended.

If histology is negative, celiac disease is excluded. If histology is positive, HLADQ2 and DQ8 testing is recommended.

Note: consider other causes for villous atrophy.

Clinical Significance

This panel of serologic studies facilitates the diagnosis of celiac disease and follows the recommendations of the American Gastroenterological Association (AGA).
