Test For Gluten Intake

I have been on a gluten-free diet for 6 years now. I recntly felt bad, aches pains, hair loss, sweating went to dr and I had low iron. She keeps threatening me with colonoscopy to rule out polyps but I think is could be due to my caeliac. I am not responding to the iron supplements, I had a feacal occult blood test which was negative. What blood tests do I ask for to check that I am not inadvertantly ingesting gluten. I have also got the pain back in my stomach I had that lead me to be diagnosed. I am in Canada and my family doc is clueless. Can anyone advise me please. Thank you

Have you had your thyroid checked recently?

I did a few months ago but my doc did not tell me the number and unless it is outside of normal she wont treat it. I was low normal before. Can that cause anaemia?

I also found out today my face powder had wheat in it.. soo not good

I think that you may need a more comprehensive thyroid test panel; because of the celiac you are at risk of autoimmune versions of thyroid problems. If your thyroid is not working well, you could have trouble with iron. I'm sorry, I don't remember the details; please read over at the Stop The Thyroid Madness for some top quality info. They can help you if you need to encourage your doc to get a clue.

I am not celiac, but I am hypothyroid and I've been big time anemic. I can relate to all of your symptoms except the stomach pain. I think your hunt for traces of gluten is very important also; but it could easily be both trace gluten and a thyroid issue.

There is a blood test to check for gluten antibodies. If they are present, you are probably still ingesting gluten. If they are absent, that doesn't prove that you are not ingesting gluten.

Have you tried a diet of only produce and meats? You could do that for a week or so to see if things improve.

Keep a food/symptom journal. Keep your diet simple so that you can track issues. Add only one thing per week because it can take awhile to notice symptoms. Good luck.

In people with elevated IgA pre-diagnosis or who were diagnosed via blood work, the AGA IgA/IgG and DGP tests for dietary compliance are extremely reliable and can be trusted upon to prove dietary compliance. If a person is symptomatic and had negative testing on re-test, it most likely is another problem not related to gluten ingestion. It may not be so useful in those who do not have an official diagnosis, for obvious reasons. If these tests were not reliable for re-testing diagnosed Celiacs, they would not be used.

You beat me to it. There are other studies too.

Maybe I misunderstand what you wrote, but....

if they are present, you ARE ingesting gluten.

if they are absent , that does not prove you're not?

so, in essence, the test is worthless?

I am seronegative myself, so follow up testing is worthless on me anyway.

But if a person was POSITIVE on blood work before DX and then going gluten-free, wouldn't it be a reliable FOLLOW UP test for that person?

(which may be what Gemini was trying to convey?)

IrishHeart, like you I am seronegative. I was put on a gluten free diet by a rheumatologist without prior referral to a Gastro, and it is now probably too late for a successful biopsy without a lengthy gluten challenge. Would you mind if I was nosey and asked if you managed to get a positive biopsy for your diagnosis, or did your Gastro diagnose you based on your extensive and severe symptoms? Just curious, if you don't mind.

Just curious, if you don't mind.

Don't mind at all! I diagnosed me, brought it back to the Primary care doc who reviewed everything with me and said "OMG, you're right!" Why he coud not see it for years everytime I went back in with symptoms is beyond me, especially since he has 3 kids with celiac. :blink:

The NEW GI doctor I went to read my various reports, saw the many errors made (including an endoscopy done--without a biopsy! <_< ), my copious notes and symptoms list, then, he took into account my malnutrition, rapid 90 lbs. weight loss, various anemias and deficiencies, arthritis, osteopenia, the horrible 3-year decline in my health, serious muscle wasting, hair loss, neurological symptoms, etc, etc, ....positive DQ2 test, family history, various AI diseases and the pictures of me before I got sick and when I was sick (I looked like an emaciated mess) etc.

His response? "I don't know how you went unDXed for so long. It's pretty obvious to me." I said "me, too Doc! :angry: I have had a hell of a fight to get someone to see it. I was told repeatedly that could not be it because the celiac panel was negative."

He was very upset. Thankfully, he has done follow up testing of all kinds and he is going to biopsy me in the Spring to make sure I do not have refractory sprue. No gluten challenge necessary.

He says falsely negative blood work happens all the time. He also says biopsies are often done wrong. And he had a patient with neither of the "so-called celiac genes" with total villous atrophy.

So much for "diagnostic criteria".

First off, I am not a doctor or any sort of medical professional. I am a PhD chemist which does not qualify me to give medical advice.

Test levels going down show that you diet is better. Test levels being negative do not show that your diet is perfect.

That doesn't mean the tests are worthless. I had them. They aren't perfect. There isn't much in this world that is.

IrishHeart - Wow, its one hell of a story. I don't know whether to envy you for eventually finding a diagnostic prince, or to commiserate the fact that you suffered for so long. I'm pretty sure I've had it since my teens or early twenties, but maybe on a "sub-clinical" level until 2-3 years ago. My health was just starting to cascade downwards in a fast, accelerating way similar to how you describe when I went gluten free and put a stop to it. I guess I was luckier than you in that we have known for 10 years that we have celiac in the family (there were 2 cases until this year, now, including me, there are 6, with another probable case still in diagnosis), we just had no idea that gluten intolerance could have such varied presentations, with widely differing levels of sensitivity.

I really, really wish that the doctors who write the medical papers summarising clinical research/experience and who have a hand in setting the clinical diagnosis guidelines would acknowledge the imperfection of the blood tests and the difficulty of obtaining a successful biopsy. Then maybe clinicians wouldn't give such black and white answers when they can't tick all the boxes that their guidelines indicate. Then maybe people like you and I (and others in my family) wouldn't go undiagnosed for so long, destroying our health in the process.

I know you have written about yourself many times on this board, in snippets, helping people with their journey. Had you thought maybe about posting a full account of your seronegativity and symptom history in the pre-diagnosis section for others to see and learn from? Maybe myself and others who have had similar experiences could add our stories it to reinforce the message? Maybe if Admin thought it was a good idea, it could even be pinned to that forum, so it didn't disappear under the weight of new posts? What do you think?

BTW - I think you and Dilettantesteph are saying the same thing about the tests. You are picking each other up on semantics!

No, I think we are just reinforcing each other, actually. :)

I think many people have written about the same issues I had trying to be DXed---that is what drew me to this Board in the first place.

I am sure my story is in the pre-DX section somewhere.

Doctors are reluctant to DX without the blood panel and the biopsy.

In the end, it comes down to finding someone who gives a crap enough to look at the patient's symptoms and to follow through with you. IMHO

Just to qualify: I meant "worthless" in regards to being VALID for seronegative people, that's all.

I am not disagreeing with you regarding the testing not being perfect nor am I disputing what you said or arguing the point.

I am saying essentially the same thing and wondering (just aloud here--I am not asking anyone to be a doctor) what can she do then to determine if she has elevated levels--if these tests are deemed "unreliable"?

I know what you mean now, I was really rushed this morning so I didn't read as carefully as I might have.

Maybe enterolab. Enterlab says that the fecal tests are more sensitive than the blood tests and pick up antibodies before intestinal damage occurs. That is their explanation for the false negatives. I don't know what to think about them. I know that some swear by them and some think that they aren't any good. We're getting follow up testing on my husband and daughter with them so maybe I'll have a better opinion at that point.

I know my daughter's blood test was negative and her fecal test positive. When she went off gluten she noticed a major effect and now she gets glutened by small amounts, but she's less sensitive than my son and I. That would be consistent with the test being valid, but that's only one case.

I know someone else who has had many follow up enterolab tests as he cut more and more cc out of his diet and becomes less and less symptomatic. His numbers eventually went down to zero. That's not my personal experience, so maybe I shouldn't have mentioned it, but it is information I considered before ordering a repeat test for my daughter. Go ahead and edit my post if I shouldn't have put that.

I got negative blood tests after a year. I don't dare get the fecal test because I don't know how much more I could do to rid my diet of cc. I'm happy if I'm symptom free. I think I don't want to know if there is still gluten in my diet. Plus, I won't know if it is from an old glutening or a current glutening unless I can stay symptom free for a long time before I give the sample. That is a challenge.

There really needs to be more done by the medical professionals in terms of developing a protocol when it comes to follow up with this condition. Each doctor doesn't things a little differently.

Sadly, the "medical professionals" :rolleyes:

say fecal and saliva testing are not valid.

Enterolab testing is being "poo-poohed". And I am not sure why, to be honest. Some say it is because "he" is not publishing and peer-reviewed. Okay, I understand that part. I really do.

Yet, the very same saliva test (for genetic testing) I did with that lab?--- yielded the EXACT same result as a fecal test (for genetic testing) by another lab --approved by my insurance---that my doctor used. It is considered "valid".

Same result, different labs. :unsure:

So what are we to do???

So many sick people. Nowhere to turn--- if the testing can often be questioned . :(

I am grateful that my GI doctor did a small bowel follow through (checking for lymphoma, etc), testing for Crohn's and other inflammatory bowel diseases and continuous lab work and is willing to scope/biopsy me ( a year plus after DX ) because I did not get the proper attention BEFORE DX.

:lol:

I think it is because it comes up with way too many positives. Fecal tests are designed to detect problems before intestinal damage occurs. That way it show positives when biopsies are negative so it considered incorrect. It's a bit of a "Catch 22"

I think that's why he seems to have gotten fed up with the GI celiac community. He wants to help people before they get terribly damaged, not after. Whether or not this is misguided, I can't say.

So many sick people. Nowhere to turn. :(

So true.

The NEW GI doctor I went to read my various reports, saw the many errors made (including an endoscopy done--without a biopsy! <_< ), my copious notes and symptoms list, then, he took into account my malnutrition, rapid 90 lbs. weight loss, various anemias and deficiencies, arthritis, osteopenia, the horrible 3-year decline in my health, serious muscle wasting, hair loss, neurological symptoms, etc, etc, ....positive DQ2 test, family history, various AI diseases and the pictures of me before I got sick and when I was sick (I looked like an emaciated mess) etc.

His response? "I don't know how you went unDXed for so long. It's pretty obvious to me." I said "me, too Doc! :angry: I have had a hell of a fight to get someone to see it. I was told repeatedly that could not be it because the celiac panel was negative."

He says falsely negative blood work happens all the time. He also says biopsies are often done wrong. And he had a patient with neither of the "so-called celiac genes" with total villous atrophy.

So much for "diagnostic criteria".

My Celiac blood test was negative. I was scoped though, and had severe villous flattening. The GI DXed me because of it. I also had pretty rapid weight loss, muscle wasting, numerous vitamin deficiencies, ostopenia, neurological symptoms,insomnia, anxiety etc.

When I went back to my PCP for follow up I was told that he didn't agree with my DX. I was "too old" and my blood test was negative.

I've had very slow healing gluten-free, and no cooperation from my PCP with blood tests, etc. I also went soy, dairy, peanut, and MSG free. Was rescoped by a different GI 6mos. gluten-free to see what was going on. Right after the procedure he said it looked like I had Refractory sprue. I was also given the genetic test at that time.

When I called to find out the results of that second scope/biopsy, I was told I don't have Celiac disease..because my gene test was negative! :o

I actually have the same genes as you IH..I think? A DQ2.2? The severity of our damage..and the slow healing is also very similar?

The blood tests are maddening to me. If the Dr. or lab don't read them right..the DX isn't made.

There's got to be a better way? Sometimes I wonder if our particular genes make us react to gluten to such a severe extent..or is there some other Celiac-like disease that we have? IMO they need to make it more common knowledge to Dr.s that the DQ2 and DQ8 aren't the only Celiac genes..and that 20-30% of Celiacs have negative blood tsts!

Right now...I'm waiting for an appointment to Mayo clinic in MN. I went to the one in FL and they referred me to the other one. My DX is still in question!

I have read your story on other threads and find this almost as ridiculous as my own experiences. :rolleyes:

I am healing my gut and resolving vitamin deficiencies, etc.-- but I still have bone/joint/muscle pain and slow regrowth of my hair. I am, indeed, a slow healer.

I do not know why your PCP finds this diagnosis to be questionable at all.

Frankly, why isn't the GI doctor who DXed you doing the follow up?? I do not rely on anyone else except my GI to care for me regarding the dozens of celiac-induced symptoms.

I went to second GI because I had SO many symptoms that weren't improving, along with a PCP that kept telling me my DX was wrong. I guess I thought a second set of eyes might be a good idea?

The second GI made my DX even more questionable. He referred me to Mayo and I figured they could tell me for sure one way or the other? Nope! :blink:

I DID get a new PCP though. She told me up front that she didn't know a lot about Celiac disease, but was eager to learn more. She said she was taking my file home with her over the weekend to review it, and would be looking up info on Celiac too.

When I went back to her last week she said at first she thought I was taking a lot of supplements, but once she got my bloodwork back she changed her mind. She said it looks like I'm on the right track, and have obviously done a lot of research into my condition. She told me to keep doing what I'm doing as I wait for my Mayo appointment.

If I need any GI follow up after Mayo..I'll be going to the first GI I saw. The second one was an arrogant *****!

:angry:

Bubba's mom. What a difficult time. I hope that you are keeping a food/symptom journal. I have gotten by with that and many challenge/elimination studies. I wish you the best. It is really too bad the experts done know more about this condition at this time. At least we haven't been told to only eat bananas like in the old days.

Thanks Steph. I was told early on to start a food log by someone here. It was how I figured out my soy and MSG intolerance. I told my PCP I was now reacting badly to soy as well as gluten, so that info might be added to my file for future reference.

After I got copies of my medical records so I could switch PCPs I found the Dr. wrote that I "had a poor grasp of my illness, and now think that I'm intolerant to many other foods". :o

My experience with my former PCP was infuriating. He dismissed my DX, then accused me of non-compliance to a gluten-free diet when my symptoms didn't magically go away overnight once I went gluten-free. Talk about mixed messages!

Please forgive my ignorance, but why isn't DQ2.2 the same as DQ2? Isn't DQ2.2 just a subset of DQ2?

Sorry if this is a dumb question, but I understand very little about the HLA typing, other than the fact that there are 2 key groups researchers say are POTENTIAL celiacs, with celiac being uncommon (but they don't know uncommon) outside of these groups?

Thanks

You are correct as far as I know. HLA-DQ2 qnd DQ8 are considered the genes most commonly associated with celiac disease. DQ2.2 is the rarest subset of the DQ2 (DQ 2.5 being the more common) and from the last article I read, it is found in 1-2 % of celiacs. When I had gene testing done, one lab report specifically said it is RARE for someone with 2.2 to develop celiac and the other lab test (my new doc ordered yet another genetic test) only reported me as --and I am quoting: "POSITIVE for CELIAC GENE HLA-DQ2". I carry two sets--one from each parent.

There is continuing research on the genetics involved. The most interesting aspect to me is that some people who have the DQ2 or DQ8 genes NEVER develop celiac and that some folks carrying genes OTHER than DQ2 or DQ8 ---DO have celiac.

Again, these are the problems with diagnostic criteria. Some literature still states unequivocally that someone WITHOUT DQ2 or DQ8 cannot have celiac because they do not have THOSE genes.

That simply is not the case.

    • Just recently diagnosed and wondering has anyone else experienced constant benching/gas, chest burning, and constipation?? 
    • and once that's happened if results are negative please do properly trial the gluten free diet regardless. So much of what you've posted suggests you're on the right track with this, results notwithstanding. Good luck!
    • Hi Galaxy, This does not mean that you don't have celiac.  You need a full panel done.  I only test positive on the DGP IgA test.  You still need tTG IgG, DGP IgA, DGP IgG and EMA.  Ask your Dr to order the rest?  Do keep eating gluten until all testing is complete and definitely keep advocating for yourself!  You deserve to feel good!! ((((((Hugs))))))
    • HI all. Blood, genetic and 3 biopsies diagnosed Celiac 2007. Spent 10 years on elimination diet of 9 foods to have stable colon and CRP. Never had bad Celiac numbers and my weight dropped 90 lbs from inflamation under control. Great cholesterol. Last two years have been adding foods. Last summer developed sharp pain in right flank, severe. After ultrasounds and MRI no diagnosis. Three back to back bladder infections and high CRP, Westergreen and Cholesterol later I went back to elimination diet for 30 days. Hard with food and starvation fear. Blood perfect again. Just wanted to share that obviously some food I added took me down hard. I am militant gluten-free and my Celiac blood work was normal throughout. Pain is gone. Anyone else experience this. Did you find out what it was and what test or Lab? Thanks to all who share here.
    • http://www.popsci.com/peppers-marijuana-gut Found this and found it interesting,  I will admit I love making edibles and it always seemed to help with my gut lol. "Your gut is something of an immunological mystery. Unlike the rest of the body, which tends to treat foreign invaders with a singular purpose—seek and destroy—the stomach cannot afford to be so indiscriminate. It exists to help fuel the body, and that means routinely welcoming foreign bodies in the form food. “If we injected ourselves with the food that we eat, we would have a massive immune response,” said Pramod Srivastava, an immunologist at the University of Connecticut School of Medicine. When our gut’s immune system starts acting more like that of the rest of the body, the gut gets inflamed and starts attacking its own cells. The end result is illness. Diseases like celiac (an autoimmune reaction to gluten) and ulcerative colitis (one of two types of Inflammatory Bowel Disease, the other being Crohns) occur when the gut’s immune system starts treating food, and our own body, like an interloper. These conditions often leaves sufferers in tremendous pain and at an increased risk of both malnutrition and colon cancer. But if researchers could figure out how to calm down that immunological response, it might be possible to create a treatment. Srivastava’s recent study in the Proceedings of the National Academy of Sciences suggests we may be one step closer to finding a cure. He found that anandamide, a chemical that the body makes naturally and that is very similar to chemicals found in marijuana, helps calm down the immune system—at least in the guts of mice. If his studies hold up in humans, he says it could eventually lead to a cure for ulcerative colitis. To understand how Srivastava came to this conclusion it helps to look at his earlier work. Srivastava found that when he exposed immune cells to hot temperatures that the cells became highly activated—in other words, the immune cells went to work. Previous studies have shown that elevated body temperatures (better known as fevers) can help immune cells work better. But what Srivastava wanted to know was why. How exactly did the cells know that it was getting hot in there? “It was known that there were certain calcium cells that open up in the nerves when they are exposed to high temperature,” said Srivastava. “So, if the hand encounters a hot stove, those calcium cells open, calcium falls into the nerve and that nerve impulse goes to the brain, and we know that it is warm or hot.” It turns out that the same calcium channel is also how immune cells knew that their Petri dishes were getting warm. If physically hot temperatures activate the immune cells, Srivastava wondered, would capsaicin—the chemical that makes chili peppers feel hot—do the same? The answer was yes. Immune cells exposed to chili pepper in a Petri dish behaved just like cells exposed to higher temperatures. But our cells aren’t exposed to capsaicin directly when we bite into a spicy dish. So Srivastava fed the chemical to mice with type 1 Diabetes (which, like IBD, stems from autoimmune inflammation) to mimic our actual exposure. Since the Petri dish experiments showed that heat and capsaicin tended to make immune cells more active, the mice fed capsaicin should have developed more diabetes than the control group. But the opposite happened. Srivastava found that capsaicin didn’t ramp up the immune cells in their guts—it chilled them out. The mice fed capsaicin actually stopped being diabetic. It turns out something else happens when a mouse chows down on capsaicin. A special kind of immune cell, CX3CR1, also gets activated. And that immune cell tends to suppress immune responses in the gut. Since the body can’t really depend on a steady diet of chili peppers to keep us healthy, Srivastava went looking to see what else binds to the same calcium channel as capsaicin. He discovered that anandamide does. Anandamide was discovered in the 1980s when researchers were trying to make sense of why our body, especially the brain, has cannabinoid receptors. Cannabinoids, found in marijuana, are part of a class of chemicals that can alter neurotransmission in the brain. Nature didn't develop those sensors just so humans could get stoned: anandamide is similar to the cannabinoids found in marijuana, but our body actually produces it. “The person who discovered anandamide had an interest in Indian languages,” said Srivastava. “And in India, the word ‘ananda’ means bliss.” Nobody knows whether anandamide actually induces a sense of bliss, but mice fed anandamide experienced the same healing effects—stretching from the esophagus down through the stomach—as mice fed capsaicin. Srivastava also discovered that when he gave mice capsaicin, it seemed to stimulate their bodies' production of anandamide. In both cases, it was ultimately the anandamide that was healing the gut, which suggests that other cannabinoids like marijuana might have a similar effect. As with all studies, there are some limitations. Srivastava’s work was done in mice, not people. But it does fall in line with anecdotes from IBD sufferers who have found that marijuana relieves some of their symptoms, and other studies that have found that people who eat chili peppers live longer. Because anandamide is a cannabinoid, it’s pretty heavily regulated—you can’t just give it to humans. As a result, Srivastava hopes to work with public health authorities in Colorado—the land of medical (and recreational) marijuana—to see if legalization has led to any improvement in colitis patients who consume edibles. If it has, that could help Srivastava make the case for a study that repeats his experiment in human patients. In the meantime? Well, if you live in Colorado and want to try something new for your IBD, you're sure in luck. But most patients should probably hold off on trying to mimic the study results at home: many IBD patients report negative reactions to spicy foods, likely because they increase stomach acid and often contain nightshade plants. So guzzling hot sauce might not be a safe way to boost your body's anandamide production."
