Celiac/gluten Intolerance And Blood Tests

Would a positive blood test occur with gluten intolerance or ONLY with celiac disease?

Do people with gluten intolerance usually have all negative tests but respond to a gluten-free diet?

Would you say with a positive blood test and positive response to a gluten-free diet that it is celiac disease?

those are all very tuff questions- especially considering that many doctors dont even know how to answer them.

it might be easier to dissect your tests if i saw which antibody tests were taken and what the numbers were.

it IS confusing because i think an official Celiac dx is just ONE aspect of Gluten Intolerance- i think Gluten can cause a VAST amount of inflammatory and autoimmune diseases.

sorry if i didnt truly answer your question...

As cassP says, you will get different answers to this question depending on who you talk to. Many doctors are still of the opinion that if you don't test positive for celiac disease you can continue to eat gluten without worry. Many (more enlightened in my book) doctors, recognize that there is such a thing as non-celiac gluten intolerance; i.e., that celiac tests are measuring one particular form of gluten intolerance, and that there are other forms that we have not yet devised tests to measure.) And yes, these people whom the tests identify as negative most often respond positively to the gluten free diet.

A positive celiac blood test and biopsy occur only with celiac disease because that is what they have been devised to measure. There are currently no specific tests to measure non-celiac gluten intolerance, although researchers have identified specific genes (non-celiac genes) that are associated with gluten intolerance. MRI's can pick up UBO's (Unidentifed Bright Objects) in the brain which produce symptoms that can mimic MS, but have been traced as reactions to gluten. There are no tests to associate most neurological reactions (like ataxia, migraines, etc) with gluten, but we know that if you stop eating gluten these things often go away.

If you are truly gluten intolerant your symptoms will usually go away in the absence of gluten, unless you have developed (due to leaky gut syndrome) additional food intolerances that your body is reacting to. This may require additional detective work to identify the offending food(s).

If you have tested positive for celiac, and your symptoms go away with a gluten free diet, then you are officially identified as a celiac. (Now, some doctors require a positive biopsy to confirm this diagnosis :o ; a positive response to the diet is not enough for them :rolleyes: )

Based on this new study, I would say anyone with a positive blood test and a response to the diet has celiac disease.

Gluten intolerance looking more and more like an inflammatory reaction to gluten. That reaction is thought to be the trigger that eventually develops into celiac in some people. In others, it looks like just the inflammatory reaction alone is enough to cause intolerance and make them feel sick from gluten.

Very interesting link, Skylark. Thank you!

Thanks, that's what I thought.

I'm new to the forum and am loving the exchange of information, thank you all of you! A couple of questions regarding testing of family members. I was diagnosed with DH and subsequently Celiac in September 2010. My dad had several autoimmune diseases, my brother was diagnosed with Celiac in December 2010.

1. Should all of my siblings and all three of my children have the initial blood test?

2. Can a blood test show negative but you can still have Celiac?

3. Are chronic migraines/headaches a possible indicator of Celiac?

Your thoughts would be appreciated!

Yes to all three questions!

I have been tested for celiac disease & have been on a gluten-free diet for over a month now. We have to wait a week still to get my results back. I have some questions if that's okay.

1. Why do most of your family need to get tested for celiac?

2. How come when I drink powerade my stomach gets upset?

3. Why does it take so long to get diagnosed with celiac disease?

4. The doctor said that if something the blood test was high enough then I don't have to get a biopsy done. If that's true then how do you get diagnosed?

Thanks for reading & I would love some reply's

1. It's a genetic disease.

2. It's full of sweeteners and other things that aren't good for you. It's possible you could also have a problem with fructose but it's likely that it just disagrees with you.

3. The American medical system isn't known for its expedience. Everything takes a long time.

4. You were diagnosed. By the blood test. If your numbers are off the chart, the biopsy to confirm is unnecessary. Since you've been gluten-free for so long, the biopsy results would be suspect anyway. You need to be actively consuming gluten for accurate tests

      Being as how you are largely asymptomatic, I would certainly advise undertaking a gluten challenge in order to get formal testing for celiac disease. We have many forum participants who become violently ill when they undertake a gluten challenge and they therefore can't carry through with it. That doesn't seem to be the case with you. The reason I think it is important for you to get tested is that many or most people who don't have a formal diagnosis find it difficult to be consistent with the gluten-free diet. They find ways to rationalize that their symptoms are due to something other than celiac disease . . . especially when it becomes socially limiting.  The other factor here is by being inconsistent with the gluten free diet, assuming you do have celiac disease, you are likely causing slow, incremental damage to your gut, even though you are largely asymptomatic. It can take years for that damage to get to the point where it results in spinoff health problems. Concerning genetic testing, it can't be used for diagnosis, at least not definitively. Somewhere between 30 and 40% of the general population will have one or both of the two genes known to be associated with the development of active celiac disease. Yet, only about 1% of the general population will develop active celiac disease. But the genetic testing can be used as a rule out for celiac disease if you don't have either gene. But even so, that doesn't eliminate the possibility of having NCGS (Non Celiac Gluten Sensitivity).

      Welcome to the celiac.com community, @ThomasA55! Before I give my opinion on your question about whether or not you should undergo a gluten challenge, I would like to know how you react when you get a good dose of gluten? Are you largely asymptomatic or do you experience significant illness such as nausea and diarrhea? You mentioned intermittent joint pain before you began experimenting with a low gluten diet. Anything else?

      This is way past due for your post.  I have Celiac and have been recovering for more than a year.  Doing well.  Used Essential oil to day to fry some chicken.  Read the label all good.  Then ate some chicken.  Here comes the gluten reaction.  I haven't had a gluten reaction since year.  I am angry.   I have been so careful with this crap and don't wan't any set backs!!!!! Good luck to you with your post.   Celiac is HELL!

      Hey everyone. I'm a young adult who had very high iron in 2024. 64% saturation 160 ferritin. In 2025 I had far lower iron. 26% saturation and 130 ferritin. I know this is still in range but it seems to be a large drop. That combined with the fact that I developed some intermittent joint pain between the two years makes me wonder if I could be celiac. My dietary intake of iron was pretty steady (mostly in the form of red meat). I did carnivore (therby eliminating gluten) for a bit after the second test and felt improvements in my joints and digestion. I still consume gluten occasionally socially, for religious reasons, and through cross contamination/food sharing. For these reasons, I would need to know if I had it, because although my lifestyle is low gluten its not at the strict level it should be if it turned out I was celiac. I will get a gene test first and hope I don't have DQ2.5,DQ2.2, or DQ8, but if I had any combination of those do you guys think I need proper screening through a gluten challenge / blood test? Other context. From 2024-2025, my b12 stayed about the same in the mid 600s folate went up slightly, but I heard it takes longer for celiac to affect the absorption of these. ANA negative, CRP low, ESR low.  I don't know how much noise exists around the saturation and ferritin, but it caught my eye and Celiac seemed like a possibility. I'm under no illusion that it is probable that I have celiac, only that it may be worth screening given my overall profile.
