    Refer to:
    ARUP Consult | The Physician's Guide to Laboratory Test Selection and Interpretation
  • Reference Range:

    Saccharomyces cerevisiae Antibody, IgA
    20.0 Units or less: Negative
    20.1 to 24.9 Units: Equivocal
    25.0 Units or greater: Positive

    Saccharomyces cerevisiae Antibody, IgG
    20.0 Units or less: Negative
    20.1 to 24.9 Units: Equivocal
    25.0 Units or greater: Positive

    Anti-Neutrophil Cytoplasmic Antibody, Atypical Pattern
    < 1:20: Not significant

    Interpretive Data:
    P-ANCA antibodies are found in 50-70% of ulcerative colitis (UC) patients, but in only 20% of Crohn disease (CD) patients. In contrast, Saccharomyces cerevisiae IgG antibodies are found in 80% of CD patients and 20% of UC patients. Saccharomyces cerevisiae IgA antibodies are found in 35% of CD patients but less than 1% in UC patients.

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