Saccharomyces cerevisiae IgG antibodies are found in 80% of Crohn disease (CD) patients, but only 20% of ulcerative colitis (UC) patients. Saccharomyces cerevisiae IgA antibodies are found in 35% of CD patients but less than 1% in UC patients. Detection of both Saccharomyces IgG and IgA antibodies in the same serum specimen is highly specific for CD.

| This test may be a useful tool for distinguishing ulcerative colitis (UC) from Crohn disease (CD) in patients with suspected inflammatory bowel disease. |
