Saccharomyces cerevisiae Antibody (ASCA) (IgA) details
What Saccharomyces cerevisiae Antibody (ASCA) (IgA) shows
Saccharomyces cerevisiae (baker's/brewer's yeast) antibodies, IgA type, are sometimes elevated in Crohn's disease, one of the two main types of inflammatory bowel disease, and are used as part of a broader antibody panel to help distinguish Crohn's disease from ulcerative colitis (the other main type) when inflammatory bowel disease is suspected based on symptoms like chronic diarrhea, abdominal pain, or weight loss. These antibodies aren't diagnostic on their own and are interpreted alongside imaging, colonoscopy findings, and other clinical information.
Tests that include Saccharomyces cerevisiae Antibody (ASCA) (IgA)
The IBD Profile is used to help rule out Crohn's disease and ulcerative colitis.
- Atypical Perinuclear Antineutrophil Cytoplasmic Antibodies Looks for atypical pANCA, antibodies against white blood cell components that are often found in ulcerative colitis, to help evaluate inflammatory bowel disease.
- Saccharomyces cerevisiae Antibody (ASCA) (IgA) An antibody sometimes elevated in Crohn's disease, used as part of inflammatory bowel disease evaluation.
- Saccharomyces cerevisiae Antibody (ASCA) (IgG) An antibody sometimes elevated in Crohn's disease, used as part of inflammatory bowel disease evaluation.
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, specifically Crohn's disease, and are associated with more aggressive disease.
- Saccharomyces cerevisiae Antibody (ASCA) (IgA) An antibody sometimes elevated in Crohn's disease, used as part of inflammatory bowel disease evaluation.
- Saccharomyces cerevisiae Antibody (ASCA) (IgG) An antibody sometimes elevated in Crohn's disease, used as part of inflammatory bowel disease evaluation.
