are you sure it wasnt bullshit?
I am actually logged into Labcorp awaiting some other test results. They have my old IBD Chrohns bloodwork on file if you want to check it out. 
Inflammatory Bowel Disease-IBD
    Test Name   Current Result and Flag   Units   Reference Interval
Saccharomyces cerevisiae, IgG   
36.4
High    Units   0.0-24.9    
Negative <20.0
Equivocal 20.1 - 24.9
Positive >or= 25.0
Saccharomyces cerevisiae, IgA   
47.6
High    Units   0.0-24.9    
Negative <20.0
Equivocal 20.1 - 24.9
Positive >or= 25.0
IgA and IgG antibody testing for S. cerevisiae is
useful adjunct testing for differentiating Crohn's
disease and ulcerative colitis. Close to 80% of
Crohn's disease patients are positive for either
IgA or IgG. In ulcerative colitis, less than 15% are
positive for IgG and less than 2% are positive for
IgA. Fewer than 5% are positive for either IgG or
IgA antibody, and no healthy controls had antibody
for both.
Atypical pANCA   
<1:20
 titer   Neg:<1:20    
The atypical pANCA pattern has been observed in a significant
percentage of patients with ulcerative colitis, primary sclerosing
cholangitis and autoimmune hepatitis.
