Casandra Test Code QD40102Version 1 (DRAFT)
Performing Lab
Saccharomyces cerevisiae Antibodies (ASCA) (IgG)
Also known as: Inflammatory Bowel Disease, ASCA, IBD
Clinical Use
Order TestUse
Antibodies to Saccharomyces cerevisiae are found in approximately 75% of patients with Crohn’s disease, 15% of patients with ulcerative colitis, and 5% of the healthy population. High titers of antibody increase the likelihood of disease, especially Crohn’s disease, and are associated with more aggressive disease. A minority of patients have only IgG antibodies to S cerevisiae.
