Test # Test Name Additional Information
0092303 Calprotectin, Fecal
2005018 Celiac Disease (HLA-DQA1*05, HLA-DQB1*02, and HLA-DQB1*03:02) Genotyping Do not use in the initial evaluation for celiac disease. Useful in ruling out celiac disease (CD) (high negative predictive value) in selective clinical situations such as:
• Equivocal small-bowel histologic finding (Marsh I-II) in seronegative individuals
• Evaluation of individuals on a gluten-free diet (GFD) in whom no testing for CD was done before GFD
0051689 Celiac Disease Dual Antigen Screen Acceptable single screening test for celiac disease. More expensive than single Tissue Transglutaminase (tTg) Antibody, IgA test (0097709) or Celiac Disease Reflexive Cascade (2008114). Positive results must be confirmed with IgA and IgG tests for tTG and deamidated gliadin peptide (DGP).
2002026 Celiac Disease Dual Antigen Screen with Reflex Acceptable reflexive screening test for celiac disease. Positive screen results reflex to IgA and IgG antibody testing for tissue transglutaminase antibody (tTG) and deaminated gliadin peptide antibody (DGP). Preferred screening test is Celiac Disease Reflexive Cascade (2008114) or Tissue Transglutaminase (tTG) Antibody, IgA (0097709) testing.
2008114 Celiac Disease Reflexive Cascade Preferred reflex screening test for celiac disease. Cascade contains all tests, including IgA levels necessary for initial serologic evaluation of celiac disease.
2001613 Crohn Disease Prognostic Panel May aid in prognostication of confirmed Crohn disease (CD). May also be useful in the diagnosis of CD.
2002247 Disaccharidase, Tissue
0050567 Inflammatory Bowel Disease Differentiation Profile Preferred test for differentiating Crohn disease from ulcerative colitis in inflammatory bowel disease.
0061164 Lactoferrin, Fecal by ELISA
0050564 Saccharomyces cerevisiae Antibodies, IgG & IgA
0020612 Xylose Absorption Test (child)
