Weak +Ve Ttg Anyone? - What Did Your Doctor Say?


The Horticulturalist

Recommended Posts

The Horticulturalist Apprentice

I posted a query previously in the forum section for kids with celiac forum here.

I called the Celiac Center at the University of Chicago a couple of days ago and they now have a faxed copy of his bloodwork, I'm waiting for a review by their doctor, it's hard to be patient! :)

These are the results for my 6yr old:

Immunoglobulin A 157 (range 87 - 474)

Tissue transglutaminase 4.9 (range <4 negative,4-10 weak +ve,10 and above +ve.

here are my questions:

1) has anyone else had Ttg come back in this 'weak positive' range, and if yes, were you - or your child - referred for endoscopy?

2)If you had a 'weak positive' Ttg did you then go on to have a +ve endoscopy for celiac?

I know everyone's case will be different and my son's results could be quite different to yours, I'm just interested in your stories.

Thanks!

Is this the only testing that they did for Celiac? There are other blood tests that should have been done at the same time, like a DGP or the older gliadin ABS. There are other conditions that can cause a positive tTg, like type I diabetes or autoimmune liver problems. I am suprised given your history of celiac in your family and your son's symptoms that the doc didn't order a more comprehensive panel. :unsure:

Keep me posted on what U of Chicago says. I live in the suburbs of Chicago, and I am considering going there with my 6 year old for Celiac testing once I get my biopsy done.

I don't have a family history of celiac, I may need to get these additional bloods done. I'll see what the Chicago people say.

If I were closer to UOC then I'd absolutely take my son there, the more experienced the gastroenterologists are the better!

Sorry, I just re-read you other post....it was a family history of RA not Celiac. I am a bit foggy tonight, as I am currently doing a gluten challenge and I just ate a big bowl of chicken and dumplings. Can you say GLUTEN? :P Oh, how I will miss dumplings..... :(

Yeah, I think I will persue U of C. My current medical group seems to be pretty clueless about Celiac, and I don't want to mess around when it's my little guy's health at stake.

Keep me posted!

Absolutely. I've had the misfortune of having several tests that I now know were useless, but I only found that out recently, and I've been gluten free for a year so an endoscopy is probably not worthwhile for me,

If I need to get an endoscopy for my son then I'll be going out of my way to find someone with experience in diagnosing celiac in kids. My local gastroenterologists were pretty hopeless so I won't be going back there.

I didn't get a chance to read your other post yet as I'm running out the door, but to answer your question here - my son (also 6) had a tTG that was considered moderately elevated (48.8 with a normal range of 0-19.9). The GI we were working with (who, as an aside, I think knows his stuff - we go to one of the top Children's Hospitals in the country and he is the director of the GI program) said there was only a 15% chance that the endoscopy would show anything useful even with the elevated tTG. As it turned out, my son's biopsies were negative - no indication of anything at all on both endoscopy and colonoscopy. We were tentatively planning a colonoscopy anyway even before the blood tests came back because we were looking for a cause for his recurrent anemia. But with the elevated tTG the GI said the endoscopy was a must, the colonoscopy was optional. We opted for both.

Thank you October for your reply. Do you have a family history of celiac? I do not, but several family members have other autoimmune disorders.

EDIT: update, just got an email from UofC Celiac Center, their doctor recommends an endoscopy for my son, based less on the weak positive and more on his symptoms (which I would say are very mild)

Will need to think about this some more.

We don't have a family history of celiac, but like you there are a variety of autoimmune issues.

If you go for the endoscopy and it shows a + for celiac then you have your answer. For me the drama of the scope prep was worth knowing for sure if he had full blown celiac. The hard part is when symptoms are mild and the scope is negative - what do you do with that? That's where we are now.

Edited to add that the scope prep was really drama mainly because we did the colonoscopy as well. The endoscopy by itself I don't think would have been any big deal at all and well worth the info it provided.

I'm curious about the U of Chicago hotline - did you just call their hotline number and they were willing to have a doc look over the results? I would LOVE a second opinion on whether to be gluten-free long-term without having to drive hours or pay hundreds of dollars for an out-of-network consult.

October,

I called the hotline earlier this week, most of the time it rang out and there was an answering machine, I did manage to speak to someone early Tuesday and I briefly gave her my history and my sons and asked if they were able to review his blood work for me, which they were happy to do.

I faxed it to them Tuesday and waited, I got an email back yesterday (Friday).

So, yes, they should be willing to look at your son's records if you can fax/email them. I don't know if they will look at previously taken biopsy slides, that would require a GI pathologist and I'm not sure if they have one on staff at the Center, but I would certainly ask.

The lady I spoke to was very nice and sympathetic, you have nothing to lose by calling them.

Have a read of this article about biopsies, I found it a bit of an eye opener. Open Original Shared Link

      Got it. Thanks Scott. I'll set up an appointment with a GI after the holidays and get all the celiac disease screening done. Thanks to this amazing forum and to all who have answered my question, I now know what my next steps are.

      Aah it sucks that there's no definitive way to confirm NCGS or celiac. I've found a GI clinic that is covered by my insurance and I'll contact them after the holidays to setup an appointment. I hope to get some sort of clarity with further tests.

      Thanks @knitty kitty. I didn't know about thiamine deficiency before you had mentioned it. I'm doing more research into what it is and how I can test for that deficiency. Is Vitamin B1 test the best way to find it? I saw that there is another test: Erythrocyte transketolase activity coefficient (ETKAC) assay to test for thiamine deficiency but I'm not sure how that test is done. Is that something I can take on my own or do I need GI referral. If it does turn out that I'm thiamine deficient, does that confirm that I have celiac disease or could it just mean that I have not been consuming Vitamin B1 rich food and once I address that with a supplement or food, I would no longer be thiamine deficient? Also full disclosure, I'm a vegetarian and only last year I found out that my Vitamin D level was very low. It was 3.7 ng/ml and the ideal range is >29.9 ng/ml. After a year of taking multivitamin supplement, my Vitamin D level has gone up to 27 ng/ml. Though it's better than 3.7 ng/ml, it's still below the range. I'm not sure for how long my Vitamin D level was around 3.7 ng/ml before 2023 as I didn't have my Vitamin D test taken prior to that. My doctor also wanted to check my Vitamin B12 level as I might not be getting enough of it from vegetarian sources. When I took that test last year, Vitamin B12 was 247 pg/ml and ideal range is 200-1100 pg/ml. So it's still within the range though it's on the lower end of the ideal range. I also have recently started taking vitamin b-complex tablets daily. I've never checked other Vitamin B levels including Vitamin B1. Do you know if such a very low level of Vitamin D and moderately lower level of Vitamin B12 would cause celiac disease or may contribute to some of the symptoms I've been experiencing? Regarding the DNA test to test celiac genes, are you referring to HLA DQ2 and HLA DQ8 tests? As soon as I got the result where my IgG was above range, I had ordered the "HLA Typing for Celiac Disease" test in Quest Diagnostics which measures HLA DQ2 and HLA DQ8. The test is 2 weeks from now and I'll post my results here once I receive them.

      Small amounts of gliadin are detectable in some samples of human breast milk but these are at too low a level to cause symptoms. No gliadin has been detected in the beef of grain-fed cattle.   https://pmc.ncbi.nlm.nih.gov/articles/PMC5622696/

      Welcome to the forum, @Kiwifruit, I agree further testing is needed.  Disaccharidase deficiency is a symptom of Celiac disease.   On your test results, this line  "IgA: 0.9 g/l (norm 0.8 - 4.0)" is referring to Total IgA and it's very low.  People with low or deficient Total IgA should also have DGP IgG test done.  Low Total IgA means you are making low levels of tTg  IgA as well, leading to false negatives or "weak positives".  Maybe a DNA test for known Celiac genes.   Anemia, diabetes, and thiamine deficiency can cause test results like these.  Get checked for B12 deficiency anemia and have your iron (ferritin) checked.  Vitamin D deficiency is common, too.   Might be time to find a gastrointestinal doctor who is more familiar with diagnosing Celiac Disease.   Best wishes on your journey!  Please keep us posted on your progress.
