Test Methodology

Interpretation

The term "inflammatory bowel disease" (IBD) is often used to refer to 2 diseases, ulcerative colitis (UC), and Crohn's disease (CD), that produce inflammation of the large or small intestines.

Patients with IBD have been shown to have antibodies in serum that help to distinguish between UC and CD. Patients with UC often have measurable neutrophil atypical perinuclear anti cystoplasmic antibodies (Atypical P-ANCA), which react with as yet uncharacterized target antigens in human neutrophils; whereas patients with CD often have measurable antibodies, which react with the Saccharomyces cerevisia strain Su 1.

Clinical Utility

As an adjunct in the diagnosis of UC and CD in patients suspected of having IBD.
