Saccharomyces cerevisiae Antibody
|Container type||Gold top|
|Amount to Collect||2 mL blood|
|Preferred volume||1 mL serum|
|Min. Volume||0.5 mL serum|
|Processing notes||Refrigerate serum, send in plastic tube, order #10295N for IgA and/or #10294N for IgG|
|Additional information||The presence of IgG or IgA antibodies against the mannan antigen of S. cerevisiae in patients with gastrointestinal complaints is
associated with a diagnosis of Crohn's disease. Although the specificity is relatively high (90-95%), the test may also be positive in small number of patients with gluten sensitive enteropathy, primary biliary cirrhosis, and Behcet's disease.
The sensitivity of the test is low (45-60%), therefore a negative test does not rule out the diagnosis.
