CICA/ Celiac, IBS, & Crohn’s Array

Connecting the Dots on Celiac Disease, Non-Celiac Gluten Sensitivity, and Crohn's Disease

The CICA is a comprehensive test array that analyzes genetic predisposition, detects specific antibodies, and measures potentially inflammatory cellular reactions all through one simple blood draw.

Celiac disease risk analysis is determined based on the presence or absence of the HLA-DQ genotypes. Both the DQ8 and DQ2.5 genotypes are tested in this array, with the DQ2.5 genotypes representing a much greater risk of celiac disease.

Four specific serum antibodies (DGP IgG/IgA and tTG IgG/IgA) are tested due to their high sensitivity and specificity for active celiac disease. The higher the antibody levels, the more likely untreated celiac disease is present.

Genetic markers, mutations in the ATG16L1 and NOD2 genes, associated with the Crohn’s disease are tested along with serologic markers for complete assessment.

Anti-Saccharomyces Cerevisiae Antibody (ASCA; IgG/IgA) are immune proteins that are frequently present in people who have Crohn’s disease. The presence of ASCA may also reflect increased intestinal inflammation and permeability, including an association with active Crohn’s disease.
