Hi all, I had two blood tests for antibodies and one was positive
Ttg IgA is 34 , weak positive is >10, positive is >20
Antigliadin antibodies IgA were negative 3,4 where positive is >10.

What does this mean?

The tissue transglutaminase (ttg) is a marker of damage in the small intestine, you are getting in the range were it becomes very specific for celiac. It can be low positive in other cases but your numbers would likely be in the 10-30 range to consider that. Antigliadin is outdated though, you were negative on it.

Going to need some more info on your clinical presentation, can you answer some of these questions:
1- What made you think of celiac, what symptoms do you have?
2- Any autoimmune in the family?
3- Any recent infections, particularly intestinal?
4- Any other stomach problems in the family?

You are going to need to do some more blood testing to see what is going on, here is the recommended and up to date tests:

Total serum IgA- Nothing to do with celiac, but if low your IgA gliadin was likely a false negative as will be with most IgA tests
Deamidated Gliadin IgA- Very specific in reaction to gluten, if this is positive with your TTG celiac is almost guaranteed
Deamidated Gliadin IgG- Accurate to its counterpart of the IgA class and is particularly useful in IgA deficient patients
Endomysial IgA- This is very specific to celiac in appropriate clinical setting, if this is positive you pretty much 100 percent have celiac

Antigliadin is outdated and considered useless to many people of the medical community, deamidated is the new and very specific version of it.

First of all thank you on fast your fast answer.
Now to answer to your questions:
1) I had diarrhea very often, two times with blood, and I went to see a specialist. gastroenterologist
2) no
3) no
4) no

Only thing I am not sure about this, cause I am 23 years old, I never had problems before. Its all coming fast.Also I think I have
candida, is their any possibility that it may have caused this problems? Most of my diarrhea are after something sweet.

It could.

At this point in time i'd insist on getting the rest of the panel ran (someone will post it no doubt) as well as an endoscopy and the genetic test.

Your levels are around what mine were (37), however i had "D" on a daily basis with vomiting happening several times a week among other things.

I am 22, not actually diagnosed yet (still might not have it) but it can come up at any age. Bloody diarrhea is not typical of celiac (usually no blood).

My suspicion earlier was with a still relatively low positive TTG without gliadin IgA positivity could be indicative of crohns disease. The fact that your diarrhea is bloody makes me lean to this more, low positive TTG is often associated with crohns and ulcerative colitis. Do you receive bad stomach pains after eating?

With these results you need the celiac panel I posted above along with Anti-Saccharomyces cerevisiae antibodies, which is the antibody associated with crohns disease. Depending on these I would recommend both an endoscopy to check for celiac as well as a colonoscopy to check for crohns and ulcerative colitis.

Both forms of IBD commonly hit at age 20-30.

So I need to do Endomysial IgA and then if it is positive its celiac 100% right?

That is correct, make sure you get the deamidated versions too.

You most likely have celiac disease with a positive ttg IgA, and your test is beyond what the lab considers to be a weak positive. :( EMA is a good test to confirm celiac disease with, but it could end up with a negative result. Not all celiacs test positive for all blood tests. In fact, some celiacs test negative on all blood tests but show upper intestinal damage on biopsy.

Celiacs are often low in B12, D, calcium, ferritin and potassium... there are others that I can't remember. You might want to get your nutrient levels checked when you see the doctor. A TSH test might be a good idea too as thyroid problems are often liked to celiac disease.

I think I read somewhere that candida shows up a bit more frequently in celiacs because of our leaky guts but I can't remember the source of that for the life of me. Sorry.

Blood in bowel movements can often be caused by internal hemorrhoids that get irritated with D or C. Hemorrhoids are fairly common in people with GI issues, although they give scary symptoms. That would be my guess for your circumstance.

Best wishes.

I forgot to ask that actually, exactly how bloody is the diarrhea? Is it a bit on top of the stool and on the toilet paper or are we talking a significant amount here? I just assumed with bloody diarrhea you meant a significant amount.

Welcome ShadowSeek-

Your tTG IgA is a clear positive - a very strong indicator of Celiac Disease.

I would suggest you request the rest of the panel to be run and then decide if endoscopy is appropriate with your doctor.

Total Serum IgA
Endomysial IgA
Deamidated Gliadin Peptide - IgA and IgG

My gut always goes with a strong positive plus symptoms = Celiac Disease, but don't remove gluten until ALL testing is complete.

Let us know how you fare with further testing or if you have more questions :)

PS...forgot to ask if you have had nutrient testing - this is important as low nutrients is another clear indicator of malabsorption caused by Celiac Disease.

Health history since celiac diagnosis became too long -- moved to the "about me" section of my profile

My children and I all have multiple copies of the genes for Celiac Disease, along with large variety of symptoms/resolution gluten-free

Current tally from me, three kids and two grands: 4 diagnosed with Celiac Disease, 2 NCGS

Get PROPERLY tested BEFORE REMOVING GLUTEN.

ALWAYS independently research health related information found on internet forums/blogs.

Actually, the AGA IgA/IgG tests are not outdated or useless. They are just less sensitive than the newer DGP ones. Many docs still use them and many people are diagnosed this way. I would ask for the DGP anyway as there was a positive tTg. Gene testing would be very helpful also.

This is accurate -- and with all things Celiac - the AGA is useful in some cases - my celiac doc still runs both DGP and AGA on me annually. If a doctor is refusing to run all the tests, I would opt for DGP.

You know, when I have blood work done every 2-3 years just to make sure I am being as compliant as I can, they never run the DGP.
It's always the AGA IgA/IgG. I was diagnosed via blood work and failed all the tests so I can use any test because there is something to compare it to but no one runs the DGP. Maybe because it wasn't around when I was diagnosed but I always find it amusing that I have to remind them there is a newer test. I have my thyroid doctor run them because she is easier to talk to.....my PCP generally just runs the tTg, which annoys me to no end because that doesn't check for dietary compliance, just damage. So many doctors still don't get it right. It's a wonder anyone is diagnosed........

Thanks for posting this thread. I also got similar results last week...but over the phone, no numbers, and just a two-minute conversation. I don't get my biopsy results for another two weeks, so I went gluten-free on the assumption that my (low? high?) tTg is a diagnosis. I have Hashimoto's and responded well to a gluten-free diet (before going back on gluten for the biopsy).

Strangely, when I searched over at the Crohn's boards on tTg results, having read the studies about it sometimes indicating Crohn's, they all talked about it as an indication of a double diagnosis, adding Celiac to their existing diagnosis.

Anyway, I'm still not sure if I should begin acting like I have a diagnosis myself. My family all has weird, unexplained issues (migraines, fibromyalgia, mini-strokes at a young age, severe acid refux) and my grandmother had severe and mysterious ataxia for years before her death (she became paralyzed and unable to speak).

I'm worried my biopsy will be negative, and then my family will continue to have problems, while if it's positive maybe they can get tested and start to feel better -- and the younger ones can avoid damage altogether. I know a negative biopsy doesn't conclusively prove anything, since the damage can be patchy, so I'm eager for a diagnosis based on blood work, so I can move onto healing my system and notifying my family.

The scary thing is that a friend of mine is eating gluten although it runs in his family because he doesn't have any symptoms yet. This is the kind of attitude that freaks me out. So of course no matter what I can't guarantee my family would take it seriously either.

At least now I think I know why I don't like the taste of waffles...! Everyone always thought that was weird of me growing up.

the thing about the biopsy is they're trying to find damage in an area that's about the size of a tennis court. It is very possible for them to miss it. Most cases, unless severe, damage is not seen with the naked eye.

Get the genetic test done, that would help your family out more as celiac is a genetic condition.
