I love google.com. I found these two abstracts, (which you can read in their entirety):
http://gut.bmj.com/cgi/content/abstract/54/9/1232 "Familial clustering of these antibodies has been described, suggesting they might be genetic markers. Our aim was to investigate the presence of these antibodies before the emergence of overt clinical manifestations".....(you can read the entire abstract)..."Conclusions: ASCA and pANCA may predict development of inflammatory bowel disease years before the disease is clinically diagnosed."
https://lirias.kuleuven.be/handle/123456789/8440 "CONCLUSION: ASCA is strongly associated with familial CD in Belgium, and 21% of healthy family members also display the marker. The association is much weaker in patients belonging to mixed families. ASCA is a stable marker and is not a secondary phenomenon due to increased intestinal permeability."
I thought my dr mentioned it could be positive because of my mom having it but maybe she didn't. Geez... i am worried. Sounds like there is a big chance I have CD. ;(
