Anti Saccharomyces Cervisae (ASCA) IgG Antibody

ANTI SACCHAROMYCES CERVISAE (ASCA) IGG ANTIBODY Test Purpose

The Anti Saccharomyces cerevisiae (ASCA) IgG Antibody Test is performed to detect IgG antibodies against Saccharomyces cerevisiae (baker's yeast) in the blood. Primarily, the test is used to help diagnose Crohn's disease, a type of Inflammatory Bowel Disease (IBD). Additionally, it assists healthcare providers in differentiating Crohn's disease from ulcerative colitis, particularly when clinical symptoms and other investigations are inconclusive. Furthermore, the test is often performed alongside other IBD-related markers, such as pANCA (Perinuclear Anti-Neutrophil Cytoplasmic Antibodies), to improve diagnostic accuracy. Moreover, the results are interpreted together with clinical history, endoscopic findings, imaging studies, and other laboratory tests to provide a comprehensive evaluation.

• Individuals with suspected Crohn's disease.
• Patients with symptoms of Inflammatory Bowel Disease (IBD).
