I've had multiple colonoscopy. But my celiac disease was Dx'd with a blood test for the DNA gene, it came back positive. It also came back positive for both my sons. They can take a biopsy of your intestine during the colonoscopy but if they don't biopsy a damaged part the test will be negative.

I understand from Nanny, here on this site, that the tests for celiac are only 40% accurate. She always suggest to get off gluten for 90 days and then slowly reintroduce gluten into your diet. If it makes you sick or gives you symptoms then you shouldn't have gluten.

Good luck in your search for better health.

i dunno... if i get off gluten (lol saying itlike thatmakes it sound like a drug addiction) and my symptoms clear up i cant imagine putting it back into my body. Maybe its cause ive been sick for so long, and i know its a matter of really knowing if its the true culprit but i just cant imagine even taking the chance that it will make me feel crappy lol. I have found my self saying that for 6 monthsi am going to beultra strict. if the package doesnt say GF on it or that its wheat free then itwont be going in our bodies. and that after that time (I think i arbatraially picked that date as i read thats a good guess at how long til my kids might feel better) i may concider an item if it says that it may possibly have it (which i interpret as its made in a factory that makes wheat stuff and might cross contaminate) but so far thats as close to being ok with it as ive gotten. PLEASE feel free to set my misconceptions straight :P (and wow that was kinda off topic lol)

With an endoscopy, the Dr. will be able to tell if the Villa in the stomach lining is damaged, therefore a positive indication of Celiac. Please do not experiment and stop eating gluten before blood tests/endoscopy. You could get a false negative reading.

They do need to biopsy and wait for pathology report. Unless you have as much damage as me. My duodenum was completely smooth. The doctor was amazed that I was still alive at all from the amount of damage.

Really hope you feel better soon.

I first had a blood test that came back positive. This led to my endoscopy for them to tell "how bad it was". They took about 5 biopsies which they used to checkout the villi. I had to wait about a week for those to come back (came back positive).

Please do not stop eating gluten, this will alter the results. My doc asked me to continue to eat gluten until the endoscopy was done and then asked me to go on gf diet after it was done.
