Can Celiac Disease cause blood in the stool?

I had a physical exam about 6 years ago that included 3 stool samples. ysis indicated blood in all 3 samples though not visible to the naked eye. A colonoscopy did not indicate anything unusual and I was told not to worry about it. Last year one of my physicians suspects that I have Celiac Disease, an autoimmune disorder characterized by a food protein (gluten) that when ingested damages the inner lining of the small intestines. I wonder if that could be the source of minute amounts of blood loss in my stools? Anyone with a similar scenario or familiar with this?
