• Acceptable single screening test for IgA-deficient individuals with suspected celiac disease.
• Preferred screening test is Celiac Disease Reflexive Cascade (2008114) or Tissue Transglutaminase (tTG) Antibody, IgG (0056009). (IgA testing recommended to identify IgA deficiency.)
• May aid in monitoring adherence to gluten-free diet in celiac disease confirmed patients.
