P/Saccharomyces cerevisiae IgG antibodies
Clinical significance
Assaying antibodies to Saccharomyces cerevisiae yeast (ASCA) is used in the róationalization of Crohn's disease and ulcerative colitis. Both disease entities belong to the group of inflammatory bowel disease and are difficult to ródifferentiate, as they have similar symptoms. The use of ASCA and ANCA (perinuclear anti-neutrophil cytoplasmic antibodiesów) antibody assays allows for non-invasive diagnosis of both conditions. ASCA antibodies are characteristic of Crohn's disease, while ANCA antibodies are characteristic of ulcerative colitis. ASCA antibodies in the IgG class are present in about 80% of patients.
