Lab Test For Celiac

I've been on this list a few years, I have celiac disease. My mom has felt for some time now that she has it too (or some sort of issue with gluten). However she is still having GI issues and has been going to her doctor. He ran blood tests for Celiac (I think 4 of them) and they all came back negative. HOWEVER, my mom has not eaten any gluten for at least a year. I told her that the tests are not even close to accurate if she has not been eating any gluten and she asked her doctor about this. His answer was you can NOT have celiac disease, the results of these tests say so.

She told him that I told her that she has to be eating gluten for the tests to be accurate and he said hogwash. She said, my daughter is sure of it, that I had read it on the internet. He made a comment about how not much on the internet is true. Sigh. But he did say show me where, on a reliable web site it says that.

So my question is, does anyone know of a place on the internet that I CAN show him that the tests won't be accurate unless she is eating gluten? I've been searching but most of what I've found is written by regular people not on medical web sites.

Any help would be greatly appreciated.

Yes I understand that but my mother is 80 and was brought up to believe in her doctors, so what I am looking for is something from a website that says you have to be eating gluten for the test to be accurate so I can show her and her stupid doctor.

Hi Susan :)

Your mom's doctor is woefully ill informed.

Can you get your hands on a copy of Dr. Green's book--"Celiac Disease--A Hidden Epidemic"?

On page 52, he states:

"A key consideration for all of the tests described is whether the patient has been consuming gluten before being tested. Results of all the tests will return to normal on a gluten free diet."

He then goes on to describe the gluten challenge, which he states "involves a biopsy, not blood tests, after a period of eating gluten".

Hi Susan :)

I am reading Dr. Green's book now and have read other books besides doing research on the internet. I was diagnosed through Enterolab like several others on this board. I have fired many GI's in my area and was not going to do anymore invasive tests like the biopsy. I've been through enough over the past 25 years! The way I understand it is if you take the blood tests they are not accurate because if you do not have any damage in the small intestine, which some Celiac people do not, then the tests are a false negative. Not all Celiac's have damage in the small intestine, but that doesn't mean they don't have the disease. Also, on the biopsy's, if the doctor doesn't get the biopsy of the tissue where the damage is at then that will also come back negative and once again it doesn't necessarily mean that you don't have it. This is how I understand it and I don't know if that is correct or not.

I did a little more research. The New England Journal of Medicine has articles of Celiac but access is limited to a list or table of contents unless you are willing to pay for the article. I assume other promanent medical journals do the same thing. You might consider getting the list of articles and heading for the nearest library that carries medical journals.

I hope the link works, this is the NIH consensus statement on Celiac disease, you can't get much more official than that, and it clearly states that all testing should be done while the patient is still consuming gluten. Hope this helps.

Wow, it amazes me that drs are so misinformed.

Amazing because the tests measure an antibody response to gluten, and those who are Celiacs, once on a strict/maintained diet, return to "normal" levels (i.e., don't look like a Celiac anymore) because there is no gluten to react to.

"A gluten-free diet should not be started until all diagnostic tests are completed, as the withdrawal of gluten can change test results." Open Original Shared Link (again, Dr. Green)

Susan, good to see you on here again :)

Thanks so much! Yeah this doctor use to be MY doctor but I changed after fighting with him for years about what was wrong with me. But my mom thinks he's the best - ugh!

Also thanks Happy girl for remembering me, I've been so busy lately I haven't posted but I do come back and read posts now and then!

The Mayo Clinic info on Celiac says a gluten-free diet can cause blood tests and biopsies to appear normal. That is a site that most doctors would consider reliable.

      Gluten related ??

      By AlwaysLearning · Posted

      If you're just starting out in being gluten free, I would expect it to take months before you learned enough about hidden sources of gluten before you stopped making major mistakes. Ice cream? Not safe unless they say it is gluten free. Spaghetti sauce? Not safe unless is says gluten-free. Natural ingredients? Who knows what's in there. You pretty much need to cook with whole ingredients yourself to avoid it completely. Most gluten-free products should be safe, but while you're in the hypersensitive phase right after going gluten free, you may notice that when something like a microwave meal seems to not be gluten-free … then you find out that it is produced in a shared facility where it can become contaminated. My reactions were much-more severe after going gluten free. The analogy that I use is that you had a whole army of soldiers waiting for some gluten to attack, and now that you took away their target, when the stragglers from the gluten army accidentally wander onto the battlefield, you still have your entire army going out and attacking them. Expect it to take two years before all of the training facilities that were producing your soldiers have fallen into disrepair and are no longer producing soldiers. But that is two years after you stop accidentally glutening yourself. Every time you do eat gluten, another training facility can be built and more soldiers will be waiting to attack. Good luck figuring things out.

      KAN-101 Treatment for Coeliac Disease

      By Russ H · Posted

      This treatment looks promising. Its aim is to provoke immune tolerance of gluten, possibly curing the disease. It passed the phase 2 trial with flying colours, and I came across a post on Reddit by one of the study volunteers. Apparently, the results were good enough that the company is applying for fast track approval.  Anokion Announces Positive Symptom Data from its Phase 2 Trial Evaluating KAN-101 for the Treatment of Celiac Disease https://www.reddit.com/r/Celiac/comments/1krx2wh/kan_101_trial_put_on_hold/

      Gluten related ??

      By Colleen H · Posted

      Hi everyone  This has been a crazy year so far... How many people actually get entire sensory overload from gluten or something similar ?  My jaw is going nuts ..and that nerve is affecting my upper back and so on ...  Bones even hurt.  Brain fog. Etc  I had eggs seemed fine.   Then my aid cooked a chicken stir fry in the microwave because my food order shorted a couple key items .   I was so hungry but I noticed light breading and some ingredients with SOY !!! Why are we suffering with soy ? This triggered a sensitivity to bananas and gluten-free yogurt it seems like it's a cycle that it goes on.  The tiniest amount of something gets me I'm guessing the tiny bit of breading that I took one tiny nibble of ...yikes ..im cringing from it .. Feels like my stomach is going to explode yet still very hungry 😔  How long does this last?! Thank you so much
