Where can i find an explanation of each test done in the serology 7 test.  Not all of my tests came back abnormal but I was wondering what they meant.

There is not a good place to get this info...basically have to go to the medical journals. But here is a summary for the ones I understand:

ASCA IgG/IgA: antiSaccharomyces cerevisiae antibodies. Both of these are antibodies against Saccharomyces cerevisiae, which is baker's yeast. More specific to Crohn's.

pANCA: Perinuclear antineutrophil cytoplasmic antibodies. These are antibodies against the inside components of human neutrophil cells. This is an auto-antibody. More specific to UC.

anti-OmpC: Antibodies against an Outer membrane protein that is on the surface of bacteria. Associated with perforating/fistulizing Crohn's.

anti-Cbir1: Antibodies against bacterial flagella. Flagella are hair-like structures on bacteria that allow them to "swim." Associated with perforating/fistulizing small bowel Crohn's.
