Yep, you need to be eating gluten to do blood tests (or biopsies) for it.

Hi. I think I need some help...quick. Many years ago an allergist told me I had a mild wheat allergy. I didn't pay a whole lot of attention to it until recently when my symptoms got totally out of control. Told my GI I thought I might have celiac disease and I am going to have blood work done this Wednesday and a biopsy the following Wednesday (have an endoscopy yearly for another digestive problem). Anyway, in early December I stopped eating anything with glutin and I feel amazingly better. The problem is, it occurred to me that perhaps my blood work and biopsy will turn up negative because I've changed the way I eat. Checked with the doctor's office to see if I should start eating wheat again for these tests and they told me it's not necessary. After reading the postings on this site, I'm really nervous that I'm going to end up with negative results. What say you all? I don't want to do it, but if it means positive versus negative results... Obviously, at this point I don't have a month to do it, but I know what some of my worst triggers are.

By the way...I am thrilled to have found this site! Thanks for any input.

If the diet is working well for you you can stick with it if you'd like but if you really want the test diagnosis then should eat gluten.

Your other option is Open Original Shared Link (depending on how long you've been gluten-free). You can order a test kit for celiac and you'll get accurate results as long as you haven't been solidly gluten-free for a few years....and I assume you haven't been gluten-free for 4 years or something :)

P.S. It's unlikely that your doctors would accept Enterolab, but many here have used it and been very satisfied. ;)

      how much gluten do I need to eat before blood tests?

      oh that's interesting... it's hard to say for sure but it has *seemed* like oats might be causing me some vague issues in the past few months. It's odd that I never really connect specific symptoms to foods, it's more of an all over feeling of unwellness after eating them. If it happens a few times after eating the same foods- I cut back...

      IBS-D vs Celiac

      Welcome to the celiac.com community, @SilkieFairy! You could also have NCGS (Non Celiac Gluten Sensitivity) as opposed to celiac disease. They share many of the same symptoms, especially the GI ones. There is no test for NCGS. Celiac disease must first be ruled out.

      how much gluten do I need to eat before blood tests?

      Under the circumstances, your decision to have the testing done on day 14 sounds very reasonable. But I think by now you know for certain that you either have celiac disease or NCGS and either way you absolutely need to eliminate gluten from your diet. I don't think you have to have an official diagnosis of celiac disease to leverage gluten free service in...

      IBS-D vs Celiac

      After the birth of my daughter nearly 6 years ago, my stools changed. They became thin if they happened to be solid (which was rare) but most of the time it was Bristol #6 (very loose and 6-8x a day). I was on various medications and put it down to that. A few years later I went on this strict "fruit and meat" diet where I just ate meat, fruit, and squash...

      oh that's interesting... it's hard to say for sure but it has *seemed* like oats might be causing me some vague issues in the past few months. It's odd that I never really connect specific symptoms to foods, it's more of an all over feeling of unwellness after  eating them.  If it happens a few times after eating the same foods- I cut back or avoid them. for this reason I avoid dairy and eggs.  So far this has worked well for me.  oh, I have some of Bob's Red Mill Mighty Tasty Hot cereal and I love it! it's hard to find but I will be looking for more.  for the next few weeks I'm going to be concentrating on whole fresh fruits and veggies and beans and nuts and seeds. I'll have to find out if grains are truly necessary in our diet. I buy brown rice pasta but only eat that maybe once a month at most. Never liked quinoa. And all the other exotic sounding grains seem to be time consuming to prepare. Something to look at later. I love beans and to me they provide the heft and calories that make me feel full for a lot longer than a big bowl of broccoli or other veggies. I can't even tolerate the plant milks right now.  I have reached out to the endo for guidance regarding calcium intake - she wants me to consume 1000mgs from food daily and I'm not able to get to more than 600mgs right now.  not supposed to use a supplement until after my next round of testing for hyperparathyroidism.   thanks again- you seem to know quite a bit about celiac.

But I think by now you know for certain that you either have celiac disease or NCGS and either way you absolutely need to eliminate gluten from your diet. I don't think you have to have an official diagnosis of celiac disease to leverage gluten free service in hospitals or institutional care and I'm guessing your physician would be willing to grant you a diagnosis of gluten sensitivity (NCGS) even if your celiac testing comes up negative. Also, you need to be aware that oats (even gluten free oats) is a common cross reactor in the celiac community. Oat protein (avenin) is similar to gluten. You might want to look at some other gluten free hot  breakfast cereal alternatives.

      After the birth of my daughter nearly 6 years ago, my stools changed. They became thin if they happened to be solid (which was rare) but most of the time it was Bristol #6 (very loose and 6-8x a day). I was on various medications and put it down to that. A few years later I went on this strict "fruit and meat" diet where I just ate meat, fruit, and squash vegetables. I noticed my stools were suddenly formed, if a bit narrow. I knew then that the diarrhea was probably food related not medication related. I tried following the fodmap diet but honestly it was just too complicated, I just lived with pooping 8x a day and wondering how I'd ever get and keep a job once my children were in school.  This past December I got my yearly bloodwork and my triglycerides were high. I looked into Dr. William Davis (wheat belly author) and he recommended going off wheat and other grains. This is the first time in my life I was reading labels to make sure there was no wheat. Within 2 weeks, not only were my stools formed and firm but I was only pooping twice a day, beautiful formed Bristol #4.  Dr. Davis allows some legumes, so I went ahead and added red lentils and beans. Nervous that the diarrhea would come back if I had IBS-D. Not only did it not come back, it just made my stools even bigger and beautiful. Still formed just with a lot more width and bulk. I've also been eating a lot of plant food like tofu, mushrooms, bell peppers, hummus etc which I thought was the cause of my diarrhea before and still, my stools are formed. In January I ran a genetics test because I knew you had to have the genes for celiac. The report came back with  DQ 2.2 plus other markers that I guess are necessary in order for it to be possible to have celiac. Apparently DQ 2.2 is the "rarer" kind but based on my report it's genetically possible for me to have celiac.  I know the next step is to bring gluten back so I can get testing but I am just not wanting to do that. After suffering with diarrhea for years I can't bring myself to do it right now. So that is where I am!
