Off Gluten-on Gluten Diagnosis

Hello,

I'm new to the board and was hoping someone could answer my question. I've been experiencing stomach discomfort for some time as well as malabsorption. I experimented with gluten-free for 3 weeks with some improvement. My GI doctor says to return to eating gluten and then go for several test (blood work, biopsy, etc.) I was just wondering if being off gluten for that time will make the results less accurate...Or, how long to I have to be back eating gluten before going for the tests?

Thanks so much!

Hi,

I was wondering the same exact thing. My situation is a little different. I had a biopsy first, went on a gluten free diet and now my doctor wants me to eat gluten for 10 days and then have the blood test. He said it would throw off the results if I had no gluten within the last 2+ weeks. Has anyone else experienced this? Also how conclusive is the biopsy compared to the blood test? Thanks alot for everyones help.. I can notice a difference just today eating gluten. I feel bloated and very tired!

The antibodies will stay in your blood for several months after stopping gluten, although the exact amount of time isn't really clear. They should reappear almost immediately after starting to eat gluten again.

As for the biopsy, that's harder to answer. If you had minimal damage, it might have faded enough not to be seen and might take a long time to come back. Or it may be patchy and they could miss the bad spots no matter what.

If you need to have the biopsy done for whatever reason, do it now before going gluten free forever. People that have posted about doing gluten challenges after being gluten-free make it sound not very fun, and the damage might not return after a short gluten challenge anyway.

As to which is more accurate, there is no real answer to that. Either a postive blood test OR a positive biopsy means you have it. You don't need both. If your doc says your biopsy was positve, but he still wants a blood test, find out why.

Ultimately it's your body. If you feel crappy when you eat gluten, you have the power not to eat it.

      Low iron and vitamin d

      Hi, I posted before about my son's legs shaking after gluten. I did end up starting him on vit b and happily he actually started sleeping better and longer. Back to my 4 year old. She had gone back to meltdowns, early wakes, and exhaustion. We tested everything again and her ferritin was lowish again (16) and vit d was low. After a couple weeks...

      Hi @Atl222 As @trents points out, there could be many reasons for this biopsy result. I am interested to know, is your gastroenterologist concerned? Also, are your blood tests showing steady improvement over the years?

      Low iron and vitamin d

      Hi, I posted before about my son's legs shaking after gluten. I did end up starting him on vit b and happily he actually started sleeping better and longer.  Back to my 4 year old. She had gone back to meltdowns, early wakes, and exhaustion. We tested everything again and her ferritin was lowish again (16) and vit d was low. After a couple weeks on supplements she is cheerful, sleeping better and looks better. The red rimmed eyes and dark circles are much better.   AND her Ttg was a 3!!!!!! So, we are crushing the gluten-free diet which is great. But WHY are her iron and vit d low if she's not getting any gluten????  She's on 30mg of iron per day and also a multivitamin and vit d supplement (per her dr). That helped her feel better quickly. But will she need supplements her whole life?? Or is there some other reason she's not absorbing iron? We eat very healthy with minimal processed food. Beef maybe 1x per week but plenty of other protein including eggs daily.  She also says her tummy hurts every single morning. That was before the iron (do not likely a side effect). Is that common with celiac?

I remember when I had my last biopsy, several years after diagnosis, mine came back with with raised lymphocytes but no villous damage, too! In my own case, my consultant wasn't remotely concerned - in fact, he said I might still get this result even if all I ever did was eat nothing but rice and water.   My coeliac blood tests were still steadily improving, albeit slowly, which was reassuring.

      Welcome to the celiac.com community, @Atl222! Yes, your increased lymphocytes could be in response to oats or it could possibly be cross contamination from gluten that is getting into your diet from some unexpected source but not enough to damage the villi. And I'm certain that increased lymphocytes can be caused by other things besides celiac disease or gluten/oats exposure. See attachment. But you might try eliminating oats to start with and possibly dairy for a few months and then seek another endoscopy/biopsy to see if there was a reduction in lymphocyte counts.
