During the test, the levels of IgG and IgA antibodies against baker's yeast are measured in the blood. Combined with other tests, this allows for non-invasive diagnosis of digestive system disorders (Crohn's disease, irritable bowel syndrome, ulcerative colitis).

When to perform the test?

The test is performed on patients to differentiate between Crohn's disease and ulcerative colitis.

Conditions:

Antibodies against baker's yeast, ASCA (IgA + IgG), are measured in the diagnosis of conditions such as Crohn's disease, irritable bowel syndrome, and ulcerative colitis.

Symptoms:

The ASCA (IgA + IgG) antibody test is conducted when symptoms such as anemia, hypoproteinemia, vitamin deficiencies (especially B12), electrolyte disturbances, aphthous ulcers in the mouth, fever, abdominal pain often in the lower right side, intensifying after meals, diarrhea with blood in the stool, and perianal abscesses and fistulas are observed.
