Overview


What is Anti Saccharomyces Cerevisiae (ASCA), IgG?

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. And because it is difficult to diagnose these diseases using biopsies, it is ideal to get the ASCA IgG test done.

Why is Anti Saccharomyces Cerevisiae (ASCA), IgG done?

In cases with symptoms like persistent diarrhea or abdominal pain, rectal bleeding, you should get yourself tested. In order to identify if you have Crohn disease or UC doctors often suggest this test.


Interpreting Anti Saccharomyces Cerevisiae (ASCA), IgG results


Interpretations

If test results show high levels of ASCA in the body, it does not necessarily mean that the person is infected with UC or CD. In order to understand which of the two diseases is affecting the patient, a pANCA test also needs to be carried out.
