It just means you aren't IGA deficient, i.e., that IGA deficiency cannot have given you artificially low scores in the individual IGA celiac antibody tests. This is explained in the article Scott linked above.

Normal range: 70 - 400 mg/dL, a little above middle of the range. So what does that mean? Thank you! I will check out that page you linked. Appreciate it! 

Well, the only thing I would conclude with would be, if you choose not to trial the gluten free diet, is to encourage you to get periodically tested, either antibody blood tests or the biopsy or both. I think it something that needs to be monitored.

So the strange thing is I don't have any symptoms at all, except the soft stools (comes and goes) which they told me was from the Lymphocytic colitis. I had some mild positives on my antibody test and one gene was positive which is what made my doctor go ahead with the endoscopy. The reason they started any of this was finding the lymphocytic colitis this past summer after I had C Diff and she said, Well....it may be from something like Celiac.... Definitely a lot to learn through all of this and I appreciate people like you taking the time to help out a stranger like me!

Well, I wouldn't rule either out. And you might consider trialing a gluten free diet for a few months to see if symptoms improve. That would tell you a lot. By the way, the incidence of other bowel diseases is higher in the celiac population than it is in the general population. And even if you don't have celiac disease, you could have NCGS. Gluten is just problematic for a lot of folks for various reasons.
