New Here With Test Results

6 posts in this topic


I went for a consult for my fist colonoscopy. The GI doctor noticed I had marked Hashimotos Thryroiditis on my health questionnaire. He suggested I test for Celiac since often Hashimotos and Celiac go "hand in hand."

Test results are back:

TT Ab IgA normal 1.2 (<4)

TT Ab IgG positive 18 (>9 positive)

Gliadin IgA normal 3.1 ( < 20)

Gliadin IgG normal 3.1 (< 20)

IgA 132 normal (71-397)

The only positive is the TT Ab IgG. He is recommending a biopsy to confirm the results. I'm thinking I should go ahead and do it, if nothing else then to spare my close relatives and kids the need to be tested for Celiac. Could the Hashimotos throw off the results? Do these results look typical of Celiac? Any help or advice would be appreciated.

(I do not have obvious GI problems so this has been a surprise....)

I have Hashimoto's and will be tested for celiac soon... Hope you get some answers!

No, the Hashimoto's would not affect the results which are measuring antibodies to gluten in the bloodwork, and damage to the small intestine when they do the biopsy.

There is no "typical" set of celiac results. It is only necessary to be positive on one of the tests. Yours is a little unusual in that you tested positive on the IgG tissue transglutaminase and negative on the IgA, but yet you make normal quantities of IgA. Normally they run the IgG only if you make insufficient quantities of IgA, but your IgA was normal. I note that they did not run the newer, and more specific for celiac, DGP (deamidated gliadin peptide) which is often run in both IgA and IgG versions.

At any rate, the biopsy is often useful to make sure that everything else is normal in the upper intestinal tract and to check the level of damage. Sometimes the bloods are positive and the EGD negative. If this happens with you, don't let the doctor tell you that you don't have celiac, because it is often missed. Make sure he takes at least 6-8 samples because the damage can be patchy and easily missed. You can start the gluten free diet immediately after the biopsy, so now is a good time to start going through your pantry for foods to donate to a food pantry, and to start thinking about preparing your food gluten free. There is a lot of good reading on this site, beginning with Newbie 101, and plenty of threads on how to deglutenize, lots of recipes, etc. Happy reading, and best wishes for your EGD if you decide to go ahead with it. :)

Welcome to the board, and ask as many questions as you want.

Thank you mushroom. I am definitely reading a lot about going gluten free and getting set-up to give it a try.

I think it is different for each person. My son had normal IgA tests and was only positive on the IgG tests. He had ZERO GI symptoms. Our only clue something was wrong was a drastic change in behavior. He didn't even complain of feeling bad, he just turned in to the devil. (age 5). His biopsy was very positive.

My blood tests were the opposite. Only my IgA tests were positive. I had all the classic GI symptoms for about 5 years (maybe triggered by my pregnancy?). When I had the endoscopy, it came back negative.

We both went gluten free and it has made a world of difference. The other two in the family seem to tolerate gluten just fine, but I do have my older son checked every couple of years to make sure.

After you complete the tests, try the diet REGARDLESS of the results.

Good luck -

Yes the TTG can be falsely positive in Hashimoto's. Before some member asks "What does a false positive really mean?" or "There are no false positives"

A false positive means that in clinical evaluation members of a certain population sample with an elevated TTG did not actually have celiac upon further testing and never went on to develop it during clinical follow up years and even decades later. YES there are absolutely false positive in antibody tests, the endomysial is interpreting a staining pattern on monkey oesophagus, the whole point is that celiac blood tests are highly unreliable unless all very strongly positive (10 times the normal range). Your test is a very low number and is typical in the false positive range, do the biopsy and report back to us what happens.


What’s the problem with diagnosing celiac disease simply by measuring the decrease in antibodies once someone switches to a gluten-free diet?

The con is that you’ll never know if a patient truly has celiac disease versus other causes for elevated antibodies. tTG are thought to be 97-98% specific, but by definition this means that 3 in 100 persons who don’t have celiac disease will have elevated tTG (biological variations, nothing more). If you consider that celiacs are 1% of the general population, it follows that out of 100 persons tested for tTG: 1 has celiac disease and 3 do not. This could mean that only 1 out of 4 of those with positive antibodies will have celiac disease as the cause. This is why you need a biopsy to confirm it.

    • Enjoy Life/ Perky's Cereal
      I am super bummed. I just went to order my breakfast staple for the last 10 years from Amazon  - my case of Enjoy Life's Crunchy Rice - over the last number of years it has gone though name and packaging changes but it has always been there for me for breakfast There is no more in stock at  Amazon so I contacted the company and found out that they are no longer going to be making any cereals. No Crunchy Rice or Crunchy Flax .  Super sad.  I need to find a replacement and i am very picky. I am looking for a simple cereal not sweet and not mushy in milk. I am not able to eat corn so it can not contain corn.  Any ideas for me? Michele

      Hi, as a Noob, I am a little intimidated by what may come to be a major change in my eating habits. My middle has been uncomfortable for a couple of years and I got no help or input from my GP so I went to a GI Dr who checked me throughly and found nothing out of sorts other than some minor irritation in my esophogus and prescribed a medication. My stomach/mid section still is uncomfortable and really disturbingly big. The GP finally suggested that I try being gluten free for 6 weeks to see if it made a difference. I have no other symptoms of gluten intolerance, as far I know. I've had anxiety issues longer than the stomach discomfort but I am having depression and lethargy so I guess I will try to rule this out. My question is, how strict does this have to be in order to ascertain that there is a correlation between my discomfort and possible gluten allergy? How stringent is the cross contamination issue, like using a toaster oven and other daily food prep precautions. Right now, eating like this for 6 weeks feels like 6 years. But if I start to feel better in a few weeks, I guess I'll make the transistion permanently, and I'd really like my gut to be normal looking, or at least not 7 months pregnant.  Female, nearly 70, 5'8", overweight at 170 lbs.  Thanks.

      Hi There, I don't know if there is a place for videos in the forum. I just watched "The Truth About Gluten" I think it is a good video. I would like to share it somewhere but don't know where it should go. Any help would be greatly appreciated.
      Here is the link if you have never watched it. Thank You,

      Hello! I am new to this Celiac website... Is there anyone out there with Celiac AND extensive food allergies? My allergies include shellfish, dairy, eggs, cantaloupe, kiwi, mango, nuts, oranges, red dye, and more I can't think of. I went to the allergist about a year ago to see why I wasn't feeling well, and once everything was eliminated, I still didn't feel well. We did more testing to find out I had celiac as well as allergies to cattle as well as rye grass (I live on a farm basically). This was back in January 2016. I recently had my endoscopy with the gastroenterologist a week ago. I have no idea what to do or what to eat... So fish and potatoes for me!
