Negative blood test but still concerned!

Hi all,

Back in September, I had stomach issues for a few weeks. My doctor said it was a virus but ordered me a blood test for Coeliac Disease as my sister has the condition. My results came back as:

Tissue Transglutaminase Antibodies (tTG-IgA) : 4.9 (5.00 - 20.00) 

Doctor said nothing to worry about. However I still have periods where I have gas and soft stools (not diahoerra). Also, my sleeping pattern has been a mess since September and I've had mouth ulcers at least twice since then too. Is it worth going back and asking for a biopsy? 

Thank you all in advance!

Before asking for a biopsy, you might ask for a complete celiac blood panel:

-Tissue Transglutaminase (tTG) IgA and (tTG) IgG
-Deamidated Gliadin Peptide (DGP) IgA and (DGP) IgG
-EMA IgA 
-total serum IgA and IgG (control test)
-AGA IGA and AGA IgG - older and less reliable tests largely replace by the DGP tests
 
-endoscopic biopsy - make sure at least 6 samples are taken
 
VERY IMPORTANT:  Keep eating gluten daily until ALL testing is complete or the tests can be inaccurate.  
 
(Source: NVSMOM -- ?)
 
Why the full panel?  The TTG does not catch everyone.   My TTG tests are always negative (even in follow-up testing).  I was positive on only the DGP IGA.  Go figure!  How did your sister test?  

 

Welcome to the forum and let us know how it goes!

I tested Negative in August on the celiac panel. My symptoms continued and I had to go back to my doctor for a follow up on my anemia.  She referred me to a GI doctor because my numbers didn't improve.  The GI doctor felt that I didn't have celiac, but she ran the genetic test to be thorough and so that we could confidently eliminate it from the list of potential diagnoses.  The genetic test  came back positive.  Since I'm having symptoms I'm getting an EGD with biopsies in a couple of weeks.  The doctor said that she rarely sees people test negative on the panel and have celiac, but it does happen, and there's no explanation to why it happens because our bodies are complex.

My take on your situation; if you aren't confident that celiac isn't your problem and you haven't exhausted all testing options, then keep going.  You only get one body and one life and nobody is going to advocate for you as well as you.

Hi, thank you for your reply. I plan on going back for peace of mind. Can you describe your continuing symptoms after your blood test please?

      Currently, there are no tests for NCGS. Celiac disease must first be ruled out and we do have testing for celiac disease. There are two primary test modalities for diagnosing celiac disease. One involves checking for antibodies in the blood. For the person with celiac disease, when gluten is ingested, it produces an autoimmune response in the lining of the small bowel which generates specific kinds of antibodies. Some people are IGA deficient and such that the IGA antibody tests done for celiac disease will have skewed results and cannot be trusted. In that case, there are IGG tests that can be ordered though, they aren't quite as specific for celiac disease as the IGA tests. But the possibility of IGA deficiency is why a "total IGA" test should always be ordered along with the TTG-IGA. The other modality is an endoscopy (scoping of the upper GI track) with a biopsy of the small bowel lining. The aforementioned autoimmune response produces inflammation in the small bowel lining which, over time, damages the structure of the lining. The biopsy is sent to a lab and microscopically analyzed for signs of this damage. If the damage is severe enough, it can often be spotted during the scoping itself. The endoscopy/biopsy is used as confirmation when the antibody results are positive, since there is a small chance that elevated antibody test scores can be caused by things other than celiac disease, particularly when the antibody test numbers are not particularly high. If the antibody test numbers are 10x normal or higher, physicians will sometimes declare an official diagnosis of celiac disease without an endoscopy/biopsy, particularly in the U.K. Some practitioners use stool tests to detect celiac disease but this modality is not widely recognized in the medical community as valid. Both celiac testing modalities outlined above require that you have been consuming generous amounts of gluten for weeks/months ahead of time. Many people make the mistake of experimenting with the gluten free diet or even reducing their gluten intake prior to testing. By doing so, they invalidate the testing because antibodies stop being produced, disappear from the blood and the lining of the small bowel begins to heal. So, then they are stuck in no man's land, wondering if they have celiac disease or NCGS. To resume gluten consumption, i.e., to undertake a "gluten challenge" is out of the question because their reaction to gluten is so strong that it would endanger their health. The lining of the small bowel is the place where all of the nutrition in the food we consume is absorbed. This lining is made up of billions of microscopically tiny fingerlike projections that create a tremendous nutrient absorption surface area. The inflammation caused by celiac disease wears down these fingers and greatly reduces the surface area needed for nutrient absorption. Thus, people with celiac disease often develop iron deficiency anemia and a host of other vitamin and mineral deficiencies. It is likely that many more people who have issues with gluten suffer from NCGS than from celiac disease. We actually know much more about the mechanism of celiac disease than we do about NCGS but some experts believe NCGS can transition into celiac disease.

      Thank you for the clarification and for taking the time to explain the terminology so clearly. I really appreciate your insight, especially the distinction between celiac disease and NCGS and how anemia can point more toward celiac. This was very helpful for me.

      Hi,  My 7 year daughter has complained of this in the past, which I thought were part of her glutening symptom, but more recently I have come to figure out it's part of her histamine overload symptom. This one symptom was part of her broader profile, which included irritability, extreme hunger, confusion, post-nasal drip. You might want to look up "histamine intolerance". I wish I had known of this at the time of her diagnosis, life would have been much easier.  I hope you are able to figure out.

      My 5yo was diagnosed with celiac last year by being tested after his sister was diagnosed. We are very strict on the gluten-free diet, but unsure what his reactions are as he was diagnosed without many symptoms other than low ferritin.  He had a school party where his teacher made gluten-free gingerbread men. I almost said no because she made it in her kitchen but I thought it would be ok.  Next day and for a few after his behavior is awful. Hitting, rude, disrespectful. Mainly he kept saying his legs were shaking. Is this a gluten exposure symptom that anyone else gets? Also the bad behavior?

      Not necessarily. The "Gluten Free" label means not more than 20ppm of gluten in the product which is often not enough for super sensitive celiacs. You would need to be looking for "Certified Gluten Free" (GFCO endorsed) which means no more than 10ppm of gluten. Having said that, "Gluten Free" doesn't mean that there will necessarily be more gluten than "Certified Gluten" in any given batch run. It just means there could be.
