Anti Saccharomyces Cerevisiae (ASCA), IgA

Anti-Saccharomyces Cerevisiae (ASCA) IgA test is used to detect ASCA, immune proteins present in people with inflammatory bowel disease. S. cerevisiae can be found in different foods and is a common yeast. The relation between the presence of S. cerevisiae and the bowel issue is not fully clear yet. If you see symptoms like vomiting, diarrhea, rashes, shortness of breath, itching, tingling in the throat, then you should consult your doctor and go for allergy tests.

The increase in the ASCA IgA and ASCA IgG antibodies is detected for this allergy in a blood test. If IgA and IgG antibodies are more than usual, the patient is allergic to Saccharomyces Cerevisiae. For the skin-prick test, a diluted allergen is injected into the skin, and it stays there for 5 mins. After 5 minutes, if the area turns red, the patient is allergic to the specific antigen.
