The blood tests are not always accurate. They can rule Celiac in, but the can not rule it out. A negative blood test does not mean that you do not have Celiac. There are the test that you should have had:

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

Total IgA level.

If you do not want to pursue further testing, you can begin the diet. A positive dietary response is a diagnosis in itself.

The blood tests aren't very accurate especially in adults, I've read. You could ask for a biopsy to see what the state of your intestine is. Were you eating gluten at the time of the blood tests?

no, actually I was gluten free since few weeks, didn't know that for blood test it is also required.

I have also B12 level done and looks like is OK, didn't see yet for my own eyes the results.

But today feeling bad, bloating and heartburn.

thanks

If you are gluten free before the tests, it might give a false negative. The same goes for the biopsy, so if you have continued to eat gluten free, that makes any more testing unreliable. Have you felt any better on the gluten free diet? Not necessarily completely better, but at all better?

not sure, I thought I did until I got hit again 2 days ago. Definitely have less abdominal cramps and burnings,

but since 2 days I feel weak and tingling plus heartburn. True is I drink some milk and buttermilk but it's not a gluten right? Never in the youth had problem with milk.

thanks

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

      I might suggest you consider buckwheat groats. https://www.amazon.com/Anthonys-Organic-Hulled-Buckwheat-Groats/dp/B0D15QDVW7/ref=sr_1_4_pp?crid=GOFG11A8ZUMU&dib=eyJ2IjoiMSJ9.bk-hCrXgLpHqKS8QJnfKJLKbKzm2BS9tIFv3P9HjJ5swL1-02C3V819UZ845_kAwnxTUM8Qa69hKl0DfHAucO827k_rh7ZclIOPtAA9KjvEEYtaeUV06FJQyCoi5dwcfXRt8dx3cJ6ctEn2VIPaaFd0nOye2TkASgSRtdtKgvXEEXknFVYURBjXen...

      IBS-D vs Celiac

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that y...

Incidentally, I don't like quinoa either. Reminds me and smells to me like wet grass seed. When its not washed before cooking it makes me ill because of saponins in the seed coat. Yes, it can be difficult to get much dietary calcium without dairy. But in many cases, it's not the amount of calcium in the diet that is the problem but the poor uptake of it. And too much calcium supplementation can interfere with the absorption of vitamins and minerals in general because it raises gut pH.

      IBS-D vs Celiac

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that you carry HLA-DQ2.2 means celiac disease is absolutely possible, even if it’s less common than DQ2.5, and many people with DQ2.2 present later and are under-diagnosed. Your hesitation to reintroduce gluten is completely understandable — quality of life matters — and many people in your position choose to remain strictly gluten-free and treat it as medically necessary even without formal biopsy confirmation. If and when you’re ready, a physician can help you weigh options like limited gluten challenge, serology history, or documentation as “probable celiac.” What’s clear is that this wasn’t just random IBS — you identified the trigger, and your body has been very consistent in its response.

      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.

      IBS-D vs Celiac

      By trents · Posted

      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.
