The Anti-Saccharomyces Cerevisiae antibodies are immune proteins present in people with inflammatory bowel disease (IBD). IBD is a group of chronic disorders, such as Crohn’s disease and ulcerative colitis. The Anti Saccharomyces Cerevisiae (ASCA), IgG test is ordered when symptoms such as abdominal cramps, diarrhoea, weight loss, fatigue, joint or organ-related symptoms, and delayed development in children are observed. IBD symptoms differ from person to person and vary over time. The ASCA IgG test helps distinguish between Crohn’s disease and ulcerative colitis. Both the diseases are found in the colon. Since these diseases are difficult to diagnose these diseases using biopsies, it is ideal to get the ASCA IgG test done. This test may also be done for providing additional diagnostic information, in cases where the clinical presentation of IBD is unclear, the presence of ASCA-IgG antibodies can aid in diagnosis; and for tailoring treatment plan.
