Laboratory assay overview
Aids in the diagnosis of inflammatory bowel disease (IBD) and the differential diagnosis of Crohn's disease (CD) and ulcerative colitis (UC); prognostic aid for clinical management of patients with CD.
When the only positive marker is pANCA, the interpretive comment on the report will read: "Suggestive of ulcerative colitis." When only one of ACCA, ALCA, AMCA, or gASCA is positive and pANCA is negative, the interpretive comment will read: "Suggestive of Crohn's disease. Pattern is not conclusive for disease behavior risk stratification." When only one of ACCA, ALCA, AMCA, or gASCA is positive and pANCA is positive, the interpretive comment will read: "Suggestive of inflammatory bowel disease. Pattern is not conclusive for any specific disease form." When any two of ACCA, ALCA, AMCA, or gASCA are positive and pANCA is positive or negative, the interpretive comment will read: "Suggestive of Crohn's disease with high risk of aggressive disease behavior (development of strictures or fistulae)." When any three or more of ACCA, ALCA, AMCA, or gASCA are positive and pANCA is positive or negative, the interpretive comment will read: "Suggestive of Crohn's disease with the very high risk of aggressive disease behavior (development of strictures or fistulae)." When all markers are negative, the interpretive comment on the report will read: "Pattern is not suggestive of inflammatory bowel disease."

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
