ANTI SACCHAROMYCES CEREVISIAE IGA ANTIBODIES

The anti-Saccharomyces cerevisiae antibody (ASCA) IgA test detects IgA antibodies against Saccharomyces cerevisiae, a type of yeast. ASCA is often used as a marker for Crohn’s disease, an inflammatory bowel disease (IBD). Elevated levels of ASCA IgA antibodies indicate an immune response to the yeast and are associated with Crohn’s disease. This test helps differentiate Crohn’s disease from other types of IBD, such as ulcerative colitis. It is valuable for diagnosing Crohn’s disease, guiding treatment decisions, and monitoring disease progression. The ASCA IgA test is often performed alongside other serological tests for a comprehensive evaluation.
