I don't know the numbers either, but have read something along the lines of "if you have CF, you are 5 times more likely to have Celiac" Don't quote me on that, but that's what I remember.
Our daughter was tested for Celiac, both blood test and biopsy. She is negative, but she has eaten a wheat free diet for several years now because she feels better when she doesn't eat wheat.
For what it's worth, our GI doc said the blood test is 85% accurate. If you get a negative on the blood test and want to know for sure you aren't missing that 15% do the colonoscopy for the biopsy.
