IgA antigliadin antibodies are not the most sensitive tests for celiac disease, as other diseases, such as allergic-related conditions, can raise these levels as well.
If celiac disease continues to be a concern, an endomysial IgA antibody should be obtained, and depending on the clinical suspicion, a small bowel biopsy discussed.
If the diarrhea or loose bowel movements continue, a colonoscopy as well as sending the stool off for analysis and culture can be discussed.

I forgot to mention that I am also lactose intolerant for the past 10 years.
Beansmomma, you may want to consider checking to see if you're carrying the (genetic) alleles that predispose you to celiac issues. If you carry the genes and you're having a positive antibody test, you could be celiac. Also consider being tested for 'cross-reactivity' to casein. It's a major protein in dairy and many celiacs find they generate antibodies to the protein. It's possible you may not be lactose intolerant, but may actually be reacting to the protein.
Many celiacs don't have what could be considered 'normal' symptoms - my husband was one of those.
