Gluten Sensitivity Antibodies Cascade
Also known as: Nonceliac Gluten Sensitivity
Use
This test is intended to aid in the diagnosis of gluten sensitivity in patients with symptoms suggestive of this condition. It is recommended for children and adults with suspected sensitivity to gluten.
Special Instructions
If reflex test is performed, additional charges/CPT code(s) may apply.
Limitations
Patients with gluten sensitivity who are on a gluten-free diet may have negative serological test results for gluten sensitivity. Antibodies to deamidated gliadin peptide and tissue transglutaminase are specific to celiac disease while antibodies to native gliadin are present in patients with and without gastrointestinal manifestations and are serological evidence of gluten sensitivity.
