ASCA(ANTI SACCHAROMYCES CEREVISIAE ANTIBODY),IGM & IGG PANEL

Home Collection

Department: IMMUNOLOGY

The ASCA (Anti-Saccharomyces cerevisiae Antibody) IgG & IgM Panel is a blood test that measures antibodies against Saccharomyces cerevisiae, a type of yeast. These antibodies are commonly found in individuals with inflammatory bowel diseases (IBD), particularly Crohn’s disease.

This test helps differentiate Crohn’s disease from other conditions like ulcerative colitis and supports accurate diagnosis.

The ASCA (Anti Saccharomyces cerevisiae Antibody) IgG & IgM Panel is performed to:

• Detect ASCA IgG and IgM antibodies

• Help diagnose Crohn’s disease

• Differentiate between types of inflammatory bowel disease

• Assist in treatment planning.

ASCA(ANTI SACCHAROMYCES CEREVISIAE ANTIBODY),IGM & IGG PANEL Test Purpose

The ASCA (Anti-Saccharomyces cerevisiae Antibody) IgG & IgM Panel is a blood test that detects IgG and IgM antibodies against Saccharomyces cerevisiae (baker’s or brewer’s yeast). These antibodies are commonly associated with Crohn’s disease, a type of Inflammatory Bowel Disease (IBD), and help differentiate it from Ulcerative Colitis (UC).

Healthcare providers often recommend this test for individuals experiencing persistent gastrointestinal symptoms such as chronic diarrhea, abdominal pain, weight loss, rectal bleeding, fatigue, or unexplained intestinal inflammation. While the ASCA Panel alone cannot confirm or rule out Crohn’s disease, it serves as a valuable diagnostic aid when interpreted alongside clinical symptoms, endoscopy findings, imaging studies, biopsy results, and other laboratory tests such as pANCA.

Furthermore, the test may help support early diagnosis, guide further investigations, and assist healthcare providers in developing an appropriate treatment plan for patients with suspected inflammatory bowel disease.

ASCA(ANTI SACCHAROMYCES CEREVISIAE ANTIBODY),IGM & IGG PANEL Test is Recommended for Individuals:

• Individuals with persistent abdominal pain and chronic diarrhea.
• People suspected of having Crohn’s disease or other inflammatory bowel diseases.
• Patients requiring differentiation between Crohn’s disease and Ulcerative Colitis.
• Individuals experiencing unexplained weight loss, rectal bleeding, or persistent digestive symptoms.
• Patients with recurrent intestinal inflammation or suspected autoimmune gastrointestinal disorders.
• Individuals with a family history of inflammatory bowel disease (IBD).
• Patients whose healthcare provider recommends advanced antibody testing for gastrointestinal disorders.

FAQs

1. What is the ASCA (IgG & IgM) Panel Test used for?

The ASCA Panel detects antibodies against Saccharomyces cerevisiae and helps support the diagnosis of Crohn’s disease. It is also useful in distinguishing Crohn’s disease from Ulcerative Colitis when used alongside other diagnostic tests.

2. Do I need to fast before the ASCA Panel Test?

No. Fasting is generally not required for the ASCA (IgG & IgM) Panel Test. However, always follow any specific instructions provided by your healthcare provider before sample collection.

3. What does a positive ASCA test result mean?

A positive ASCA result may indicate an increased likelihood of Crohn’s disease, particularly when accompanied by compatible symptoms and other diagnostic findings. However, the test alone cannot confirm the diagnosis. Your healthcare provider will interpret the results along with your medical history, physical examination, endoscopy, imaging, and other laboratory tests to reach an accurate diagnosis.
