Saccharomyces cerevisiae Profile
Also known as: ASCA, Crohn's Disease
Use
Semiquantitative detection of anti-Saccharomyces cerevisiae antibodies (ASCA) of the IgG and IgA classes in human sera. This assay is intended for use in the diagnosis of patients with Crohn's disease.
Special Instructions
Ensure that the serum specimen is free from bacterial contamination, hemolysis, and lipemia. This test requires precise specimen handling to maintain accuracy and reliability of results.
Limitations
Interpretation of results should be done in conjunction with clinical findings and other laboratory tests. While the presence of ASCA can be significant in the context of Crohn's disease, it should not be solely relied upon for a definitive diagnosis without considering other clinical and diagnostic information.
