Anti-Saccharomyces Cerevisiae Antibody (ASCA) Test for CD and UC

The Anti-Saccharomyces Cerevisiae Antibody (ASCA) test helps doctors tell two common gut problems apart: Crohn's disease and ulcerative colitis. It's like a detective tool for tummy issues. When you have tummy troubles, this test helps figure out what's causing them.

ASCA Test

Here are the basic details of the ASCA Test.

*ASCA Test Price range may vary as per location, lab type, and procedure of lab test.

ASCA Test Means

ASCA Test is a diagnostic tool for distinguishing Crohn's disease (CD) from ulcerative colitis (UC) in inflammatory bowel disease.

• This blood test detects anti-Saccharomyces cerevisiae antibodies (ASCA) in the bloodstream, helping with IBD diagnosis.
• It plays a vital role in determining the appropriate treatment and management for patients with IBD.
• ASCA Test results, along with other IBD tests, guide healthcare providers in making an accurate diagnosis.
• This test is a valuable tool for understanding and differentiating between CD and UC, leading to more effective patient care.

ASCA Test Purpose

The purpose of the ASCA Test is to:

• ASCA Test helps differentiate Crohn's disease (CD) from ulcerative colitis (UC) in cases of inflammatory bowel disease.
• This blood test detects anti-Saccharomyces cerevisiae antibodies, aiding in the accurate diagnosis of IBD.
• ASCA Test assists healthcare providers in determining the most appropriate treatment strategy for IBD patients.
• It plays a crucial role in guiding the management of patients with CD and UC by distinguishing between the two conditions.
• The purpose of ASCA Test is to provide a clearer understanding of IBD, enabling tailored and effective patient care.

Before Test

• No specific preparation is needed before an ASCA Test.
• You can eat and drink as usual before the blood draw.
• Inform your healthcare provider about any medications or supplements you are taking.

ASCA Test Result

Here is the basic meaning of ASCA Test Result.

• Positive ASCA result: Suggests a likelihood of inflammatory bowel disease (IBD), but not a specific diagnosis.
• Negative ASCA result: Doesn't rule out IBD, CD, or UC, as some individuals with IBD may have negative results.
• Interpret alongside other tests (e.g., pANCA) for a more accurate diagnosis and to distinguish between CD and UC.

ASCA Test Normal Range

ASCA Test Interpretation

Here is the Interpretation of the ASCA Test.

The ASCA test measures ASCA antibodies in the blood to aid in the diagnosis of Crohn's disease, with results categorized as negative, equivocal, or positive.

ASCA Test Positive Result

Here are the potential causes of positive ASCA Test.

A positive ASCA test result is often linked to Crohn's disease, but it can also occur in other gastrointestinal conditions and autoimmune diseases, requiring further evaluation.

ASCA Test Negative Result

Here are the potential causes of negative ASCA Test.

A negative ASCA test result typically indicates Crohn's disease is less likely, but it doesn't rule out other gastrointestinal issues like ulcerative colitis or different conditions.

Specimen Requirements For ASCA Test
