About this test
The ASCA IgG Antibody Test detects IgG antibodies against Saccharomyces cerevisiae. It helps in the diagnosis of inflammatory bowel diseases.
ANTI SACCHAROMYCES CERVISAE (ASCA) IGG ANTIBODY
The Anti-Saccharomyces Cerevisiae (ASCA) IgG antibody test is a blood test primarily used to distinguish between Crohn's disease (CD) and ulcerative colitis (UC) in patients with inflammatory bowel disease (IBD).
The ASCA IgG Test is performed to:
Assist in diagnosing Crohn's disease
Differentiate Crohn’s disease from other inflammatory bowel diseases
Support the diagnosis of inflammatory bowel disorders
Monitor disease progression
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.
ANTI SACCHAROMYCES CERVISAE (ASCA) IGG ANTIBODY Test is Recommended for Individuals:
Patients with symptoms of Inflammatory Bowel Disease (IBD).
People experiencing chronic diarrhea, abdominal pain, or persistent digestive symptoms.
Individuals with unexplained weight loss associated with gastrointestinal disorders.
Patients with suspected ulcerative colitis requiring further differentiation.
Individuals with a family history of inflammatory bowel disease.
Patients undergoing evaluation for chronic intestinal inflammation.
Individuals referred by a gastroenterologist for autoimmune gastrointestinal antibody testing.
Anyone advised by their healthcare provider to investigate Crohn's disease or other inflammatory bowel disorders.
FAQs
1. What is the Anti Saccharomyces cerevisiae (ASCA) IgG Antibody Test used for? The ASCA IgG Antibody Test detects antibodies against Saccharomyces cerevisiae. Additionally, it helps diagnose Crohn's disease and differentiate it from ulcerative colitis.
2. Do I need to fast before the ASCA IgG Antibody Test? No. Fasting is generally not required before the ASCA IgG Antibody Test. However, you should follow any preparation instructions provided by your healthcare provider.
3. What does a positive ASCA IgG Antibody result indicate? A positive result may support the diagnosis of Crohn's disease.
